One of our members replacing the clasp on a broken bracelet. A slightly fiddly soldering job, but turned out nicely!
With the Hackspace having a collection of three different 3D printers and with them all being kept in one multi use workshop, it soon came apparent that we needed a way to keep the dust of of them all whiles also allowing us to gain easy access to them for maintenance. There was an ideal place in the workshop between the workbench and tool board where a cabinet would sit nicely.
With this in mind I took some measurements of the area and make a few rough sketches on paper. The cabinet would be 1200 x 600 x 2000 it would be divided up in to 6 quadrants, the top 4 quadrants will be where the 3D printers would be housed and the bottom two would
create storage space for reels of filament and other consumables. At the rear of each of the 4 printer quadrants there would be a 2G plug and RJ45 socket as each of the printers will run of OctoPi allowing the printers to be controlled remotely on the network. Once I had a feel for what the cabinet was going to look like on paper I drew up a 3D model using Free CAD.
The material of choice was 18mm construction ply, for the method of joinery I went for rebate joints. Each of the panels that the shelf’s and back would sit in had a rebate grove in the width of the ply routed down the width of the panel at the corresponding heights of the shelf’s the rebate was half the depth of the material. The cut away below shows half of the cabinet and how it is assembled. With the CAD design complete I got to work ripping all of the ply down to size ready for routing.
To ensure that all of the rebates where routed consistently I used a straight edge to guide the router on all the parts. By scoring each side of the rebate joints with a sharp knife before routing prevents tear out from the spinning cutter leaving a nicer and smoother finish. For routing the rebate on the perimeter of the back the router was used with it’s fens, the fens was set to the correct width from the cutter to the edge of the work piece and run down the edge.
To assemble the cabinet the shelf’s where first glued and nailed on to the two sides, this step was completed first because you could only get a run of nails in one side of the middle. The middle and top where then joined the same way followed by the back. After a sand and coat of varnish the cabinet was ready to be moved in to the workshop.
Once the assembly was complete I decided to add some pull out shelf’s on rails, this would make it easier to remove things from the print bed and gain access to the back of the printer for maintenance.
To make the door frames I created a central groove using a table saw in several lengths of 20 x 35mm PSE timber. This grove would be where the perspex in the centre of the door would sit. The rails and stiles where cut to the correct length and a tenon was made on the end of both of the horizontal rails. The perspex sheet was cut to size and the frame was glued up using a pair of sash clamps. I used piano hinge to hang the doors, this was mounted on to the cabinet first.
All that was left to do now was install the rest of the doors, give them a coat of varnish, wire in the electrics and mount the pull out shelves. With the 3D printer cabinet approaching completion there where a few things that I could have done differently and some things that could be improved or even added on. One thing that could be different is the method of joinery, there are a multitude of different ways that it cold be done the other witch I looked in to was finger joints. Finer joints provide a larger surface area for glue to stick to but are more time consuming. I ended up using rebate joints because they where more suited to the design, not only that but would also give me more experience for the next job where I could attempt something a little more complex with the skills I have learnt.
Something else that would have helped during the build process is to have made a jig that could be set over the rebate and clamped down that the router would sit in and slide across, making the process of routing the rebates much more efficient and accurate quicker. A later addition that I intend on adding is a set of castor boxes for the bottom two quadrants witch will make it easier to retrieve consumables. Overall it has been a fairly successfully build. The cabinet itself is very sturdy and provides the purpose it was intended for it also provides more storage areas both on top of the cabinet and down below in the two quadrants.

SHH&M are proud to announce that we’re officially incorporated as a company! We’re a member-run, non-profit Community Interest Company, with the mission of “helping people in Sheffield to make creative use of technology and tools for hobby-scale projects in fields such as computers, machining, technology, science, and digital or electronic art”.
More simply, we’re a Hackspace for Sheffield.
These are very early days for us, but if you’re interested get in touch!
At the moment, we’re busy renovating our new home in the Portland Works in central Sheffield. Our first proper public events will be very soon!
The Sheffield Hardware Hackers and Makers now has an official logo, with thanks to John. Over the weekend he created us a fantastically, well thought out and prestigious logo. We can now put a name to our face and start to show who we are.
I think that we can all agree that a large laser cut version of the logo is on the TO DO…. and maby even with some key rings… 🙂
Don’t forget! There is an Open Lab Planned for Saturday the 15th in the Refab Lab at Access Space.
On december the 14th we had our monthly build day at Access Space. We had a large array of 3D printers and electronic projects being worked on, some of the things that went on throughout the day include...
- 3D Printing parts to improve the hack space - Laser Cutting - Tinkering with electronics 3D Printing parts to improve the hack space
We have been hosting our meet-ups at Access Space for around 9 months now. From the start Access Space has very kindly given us a space in there Refab Lab for us to store and use our 3D Printers. We where asked to put forward suggestions for in ways witch we could improve the hack space. We discussed with Access Space about making it an easier space to work in. We decided to create and print some coat hooks. We drew up some 3D coat hooks in Open SCAD, a free open source 3D CAD programme.
Once the object had been Compiled and Rendered it was exported as a STL file, it could then be sliced and printed. altogether we printed four of the coat hooks, in total we had three printers on the Job. Including the small foldable, portable printer that has been made by one of the group members (we will try any get picture).
This above is this is the finished product. The coat hooks where mounted on to a pice of wood witch was screwed on to a shelving unit. Laser Cutting
One of the 3D printers that was brought along to the build day was a SUMPOD Delta, this printers X,Y and Z axis sit on three threaded rods. Some pieces where designed using Ink Scape (a 2D open source CAD programme) and laser cut. The pieces where to mount the stepper motors on to the printer.
Among all of this we also had some people with Arduino's creating projects, including light synthesisers. We would also like to thank Access Space for providing us with a work space and access to tools and machinery in there Refab Lab. The next meet up will be held at Access Space on the on January the 27th. You can keep in contact with us by following us on Twitter @SHHMakers or on our forum at: https://groups.google.com/forum/#!forum/sheffield-hardware-hackers
This meet up we had many things to be discuss. Some of the things that we went through…
-A review of the Hacker Day at the Hallam University
-Festival of the Mind 2014
-3D Printing in Sheffield
-When the next build day will be held
Following a successful Hacker day at Hallam University we returned to Access Space. At this event we had met a fair few number of new people who showed interest in the group.
Because the Mendel 90 had been transported around it needed some work doing to it. The printer did not seem to be homing it’s Z axis. It was soon apparent that one of the cables for the Z micro switch had worked its way off. This was an easy fix, the cable was re-soldered on to the micro switch. When we tried to home all of the axis, the Z axis did not want to move at all. On closer inspection, the right hand threaded rod was screwed in so tight at the bottom that the stepper motor was unable to move it. Once we had loosened the threaded rod the z axis were free to move. Before we were able to move the machine the Z axis needed to be levelled we did this by positioning the Z axis at about 100mm above the heated bed. Then using a spirit level placed on top of the extruder assembly, the Z axis was levelled by twisting the coupling on the threaded rod.
We then cleaned out the extruder this was done with a small piece of flexible wire bent in to a long U shape. The extruder was then heated up to temperature. The extruders idler was then removed and the hobbed bolt was cleaned. The thin wire was then inserted down the extruder. The extruder was then turned off and left to cool by 20°c. The wire was then removed from the extruder. This process was repeated several times. Once we had completed that we reassembled the extruder and pressed print. It worked just as new!
We also had a discussion about Festival of the Mind 2014, the themes for next year are:
We talked about doing something along the lines of hacking and maybe some Arduino projects, but they were only things that we drafted up at the meet up. If you can think of any other ideas regarding Festival of the Mind 2014 then let us know on Twitter @SHHMakers or our forum.
3D Printing in Sheffield
We only recently found out about a company called ‘We Do 3D Printing’ who are based in Sheffield, they sell items and components for 3D Printers. The company has a online shop set up on eBay. Because of where Sheffield is located it is an ideal focal point for collaborating on projects as well as having places to use 3D Printers and Laser Cutters.
Next Build Day
We now have a build day planned for the 14th of December between 10am to 4pm. You can bring along your projects, get advice from other group members and have access to the Refab Lab in Access Space with the Laser Cutter, CNC Router, 3D Printers and more.
Let us know if you are coming ether by our forum or on Twitter @SHHMakers.
This Months Meet Up
This meet up on the 29th of July, we had a man from BBC Radio Sheffiels come in and interview people about 3D printing. This was to try and get an understanding of what 3D printing is, how it works and how it has progressed over the years.
It was broadcast at 6:50 AM and in more detail at 7:30 AM. The show is available on iPlayer.
The 6:50 AM part is available hear at 1 hour 50 minuets.
Then the 7.30 AM part is available hear at 1 hour and 3 minuets.
The Sheffield Hardware Hackers and Makers group have a build day on the Saturday of each month, and a evening meet up on the last Monday of every month. There will be no meet ups or build days in August because Acsess space is closed. Normal meet ups and build days will return in September.
At this months meet up of Sheffield Hardware Hackers and Makers we have had Laser Cutting, 3D Printing and more
With the laser cutting a sign was cut out that said “Sheffield Hardware Hackers and Makers” this sign was made to put over where the 3D printers where. The sign had the text engraved on to the wood and the word Sheffield was cut out over the engraving.

The 3D Printing
With the 3D Printer we printed a small android logo. This was from a Gcode file, This was used as a test piece. In total Access space has three 3D Printers. It’s own, and the two that the maker group brought over. Meany things have been printed on this printer, things like parts for other printers.

The print close up
In total the print took around 18 minits to print.
Sheffield hardware hackers latest meet up
This week on the 25th of march was our third meet up of the year. This month a number of things took place.
– Whats been going on/admin
– What projects people are getting involved in
– Set up of mendel 90 3D printer and installation of software
– 3D Printing
– Laser cutting
One of the first things that took place was the set up of the mendel 90 and the installation on the software. A computer and place
were kindly provided by access space. Print run (https://github.com/kliment/Printrun), Arduino IDE (http://www.arduino.cc) as well as
one or two overs where the programs that where installed. After a bit of tinkering we got the printer working.
There was also the laser cutting, a fan plate for the coffee can filter (more to follow on this) was cut. This was the final version that was designed using ink scape. The fan plate has a 150mm diameter, a hole for the fan, screw holes, and space for a 16mm cable gland.
