Consider to follow if you like what I do. Just ask if you have an idea to a brick piece you want to be made. As the title says. Make your own version of the gears. This pack contains all the gears from 17t to 39t. I have only tested a few, but they're all made with the same specs with the gear generator so they should work fine. Printsettings layer height: 0.1, initial can be 0.2, but then you'll get a small elephant foot Perimeters: 12 (just to be sure it only using lines, no infill) Speed: 20mm/s https://www.youtube.com/watch?v=gTumwM-vLK4
