himoto barren 1:18 (gear changes)

thingiverse

Pair of gears for Himoto Barren 1:18. The original gears are very thin, making them impractical to print directly. I damaged the metal pinion, so I took the initiative to modify the pair, increasing the module of the gears, which soon allowed me to print. I used ABS and with lubrication they work well, I believe that nylon is even better suited for this purpose. It may be necessary to adjust the scale of the pieces (0.2 to 0.4%) so it's best to print two pairs with different scales. Regulate the speed in the channel because these gears make your cart go much faster.
