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
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.

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.
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.
