Kyosho Ultima ST GP rear shock mount RS-10/UMW-106

thingiverse

This is Kyosho Ultima ST GP rear shock mount/shock tower. My version is 1mm thicker than original, measuring 6mm thick compared to the stock 5mm. Keep in mind that this extra thickness won't affect the suspension geometry but might impact the fitment of the rear battery holder bracket if you're using Type-R or EVO holders. I can confirm that with a standard racing sports battery holder, there are no issues with fitment, but I'm unable to verify compatibility with -R and EVO style holders since I don't have access to original parts. This part bolts onto every Ultima ST chassis without any problems. The design is identical across the Racing Sports/Type-R/EVO versions, with the only difference being the amount of fibers used in plastic production. To achieve the right level of stiffness for this part, you can experiment with infill/filament combinations. I used 20% CF/80% PETG filament with 100% infill to print my own part, which turned out much stiffer than the original RS-10. Only small supports are required for the body pin area (the sphere on top of the part where the body holder clip attaches). Enjoy and drop a comment if you'd like me to make any changes or if this worked well for you.
