This is actually my second print of this! Both prints are mounted on tables + working swimmingly! You obviously need 4x every model but the shaft, of which you only need 2x. I printed the large gear in vertical orientation + with 100% infill. The "shaft" I printed horizontal with support, but it's the only file that needed it, and only in horizontal orientation. The rest can just be printed no-supports at 15% infill. Heated bed is always best, even with PLA - 65C.
