For the last year, we’ve been running a version of the two-shelf system, in which items left around the space are put on the shelves for collection or eventual disposal.
Does it work? Kind of. Lost items are reunited with their owners. Unused items inspire new projects. Semi-regular photos let members check the shelves from afar, workspaces are cleared with impunity, and there’s a slow but steady flow of junk out of the space.
TOG’s laserjet printer was mostly working, but the two buttons on top were stuck and unusable. Each button was supposed to have a little right-angled lever connecting it to its microswitch. The problem was that one lever had come out of its mounting, and the other one was missing altogether.
Missing. Gone. Not rattling around inside the printer, or sitting in a corner of the classroom. Just gone. But we have one lever left. If only there was some way we could make a copy of it…
The part is composed of a few straightforward shapes which were modelled in OpenSCAD.
The first print didn’t work because there was too much of an overhang. The second, improved design didn’t stick properly to the bed (small fiddly prints benefit from a brim). The third one came out nicely.
After cutting away the brim and overhang support material, the new part fits under the button…
… and the printer buttons are working again.
(And if your HP2200dn has also lost its button levers, the STL file is up on Thingiverse.)
TOG’s entry in their giveaway described how we could create 3D printed parts for the TwitterKnitter – and then share the designs so that anyone with a knitting machine like ours could print a TwitterKnitter add-on. LulzBot, who are all about open hardware, liked the idea enough to select TOG as one of 12 winners. We’re anxiously waiting for the TAZ to arrive and planning more printed projects…
One of TOG’s projects for the Dublin Mini Maker Faire 2013. This 40 year old, entirely mechanical knitting machine was upgraded with servos, electronics and laser cut parts, and spent the day knitting tweets sent by attendees.
