RC10T4 Rear Caster Blocks

These are my own design rear caster blocks to fit the RC10T4. They use 3/8" x 3/16" bearings and the standard ball end and hinge pin. I printed a set and installed them on my T4 with quite good success. I used a 7/64 drill bit to size the hinge pin hole to fit. I also tapped the ball end hole with a 4-40 tape and used a Uni-bit type step drill to make the bearing bores fit properly. You may not have to do any of this if your printer is better than mine.

Comments welcome.
