Kyosho Ultima ST Racing Sports GP slipper hub RS-153

thingiverse

Just a basic, stock RS-153 slipper hub. These parts typically wear out at the point where they make contact with the brake disc. I added reinforcement to several areas to increase durability. This part should also fit the original Ultima RB GP, but I recommend verifying this information as I don't own an RB car or manual. It works well with a stock brake disc and stock spur gear, and also with my custom spur and brake disc. These parts are notoriously difficult to find nowadays, making this new hub a welcome solution. It eliminates any unwanted play caused by a loose brake disc. Print this part using heat-resistant material. I strongly advise against printing it from PLA. No supports are needed, as the print orientation is correct in the .stl file. However, you may need to clean up the center hole of the inner side part with a 5mm drill bit, depending on your print settings. Update! The first version I uploaded was actually a modified one for my thicker spur gear (not yet released). Sorry for the mistake! I've removed that file and uploaded the correct one to Thingiverse.
