Summary

I designed this ring to put inside Kyosho legendary series Scorpion rear tyres and use them with Marui Hunter and Galaxy rims: the ring will be locked laterally by the two parts of the rim, and will lock the tyre against the half rims. Kyosho Javelin/Optima legendary series tyres will work as well.

Please note that I did not test run this with the tires on a rim. I only proof of concept it. It works with the original Kyosho insert in the tires in the addition to the internal ring, although the half rims are quite difficult to pit in place with this ring printed in PLA.

A ring printed in TPU should work as well, and allow for an easier placement of the half rims.

Please note this is still work in progress
