I'm just getting started with this whole process, and besides one line about sourcing filament in one of the manuals, I haven't seen much discussion of it. What filaments have you printed yours with? Also, looking at photos of existing builds of the Goodman cameras on the web, Instagram etc., I've noticed that there are several non-black plastic prints out there (a yellow, a red, and a marbled white, specifically.) Does anyone know if there are any issues with light-tightness that might arise from using a color other than black for the camera body?
I've created a pinhole shutter, primarily for my own use on some experimental cameras. When I put the design together, I made it compatible with the Goodman One bellows. Assembly uses some M3 and M2 screws I had available, as well as some 2mm x 1mm disk magnets I got specifically for the purpose of giving the shutter a snappy action and holding it in place. The assembly uses a 20mm pinhole disk as is commonly available on the eBay. Here are the files: https://www.thingiverse.com/thing:3555844
