Tandy/TRS-80 Model 100 battery cover

thingiverse

Battery cover for the Tandy 100. It's a tight fit because it was designed to print in PLA, and I wanted to make sure that there was a decent amount of plastic at all of the stress points so that it won't break apart under normal use. If you don't mind that, you can print a replacement battery door yourself. Print Settings Printer: Monoprice Maker Architect Rafts: No Supports: No Infill: 10%, unless your printer tries to infill the catches, which should be more like 100% for structural integrity. Try 10 and see if it works; the catches are probably too small to be infilled anywhere. Notes: I'm actually not sure about the rafts. I used the "skirt" option in Slic3r, which I'm trying out at the moment, and that worked fine. If it peels up around the edges, add rafts. Sufficient supports are built-in. Post-Printing Nothing serious. Just be very careful triming the supports out, the rear catches are still a bit fragile and can be pried apart from the door if you've got a big enough knife. How I Designed This Took a bunch of measurements of an actual battery door from another unit, threw them at OpenSCAD, and got a quick mock-up. After that it was just a matter of measuring actual fit and rigidity of the part, and adding plastic until the clips held up when the part was snapped on and off of the system.
