About this 3D model

Learn while having fun! New small gear system. my first. With 4 identical toothed wheels. I took a large module voluntarily. 2.5 Dp = mxz Dp = 2.5 x 16 (16 teeth) Dp = 40 The gear is very strong. I put spring brakes on the main axles, for a more rigid joint. Three wheels in place = locking! Four wheels in place, it turns. Easy to print, allows to have fun, there is no play in the sprockets. You can print on a smaller scale if you want. You can continue with more wheels if you want. NOP21
