Sakura Racing D4 Rear Belt Tension Pulley V1

thingiverse

I recently purchased a brand new rear drive belt for my Sakura D4 R/C drift car, and I was unable to find any suitable tension pulleys for sale so I designed this one on Tinkercad. It utilizes the original screws at the rear of the chassis that secure the shock tower on the motor side but requires 4x M3 screws (length is not crucial, but 7-10mm should be sufficient). Additionally, it calls for 2x 10mm outer, 5mm inner, 3mm thick bearings. The height is adjustable as well as the lateral position with the mounting holes for the axle, and fine tuning can be achieved with the vertical sliding slots. I have not had an opportunity to print this yet so there will be further versions if improvements need to be made. Feel free to let me know if there are any areas that I should focus on. Edit: more holes were added and a sharp point was removed. Both files are available.
