?I didn't know there was a files section. That's really cool. I just uploaded a folder with all of the parts. I intended to shorten the cord leading to the reader's head on the first design, but when I broke open the casing, I found that the wires that attach to the board are 28ga and less than 2mm apart. My soldering skills aren't that good, so I designed a taller one with more room in the cavity to hold the cord. I uploaded both designs, so if your soldering skills are better than mine, the lower profile one is there also. The reader head insert file is a small insert to go in the holes on the reader head so it can be attached to the frame. You will need to run a 2mm tap through them. You can attach the bolt running through your flip stop with an 8mm heatset insert. The bolt and the insert have to align perfectly, so the insert has to go in straight, but it's not a problem if you use good inserts. The two holes in the front are so you can fit a small #0-2 screwdriver through to tighten the screws. The screws I used are McMaster Carr # 91305A102 and the heatset inserts are #94180A386. The mag tape insert file is for helping to align the tape in the center of the tracking.?
