1/10 Mattracks i made for my rc car and the 3d printed truck from "MrCrankyface" use m3 screws, and bearings i use two 10x15x4 in 1 mattrack,total of 8
...Zeig mehr bearings, use one bolt on the rear of the frame as a limiter for the rear wheels. Belt is printed with flexible filament and doesn`t need any support.you may have to drill up some holes to make them bigger for the m3 bolts. if you have any improvements i should make just comment! happy printing!
