Roller Wheel for OrangeRx T-SIX or Spectrum Rx

The roller wheel broke on my new OrangeRx T-SIX from Hobby King, I had already done a mod with the battery compartment so no way I could send it back so I decided to design my own in Sketchup

Print at 100% infill or as I did .. 10 wall counts

Black one is printed in PET-G and the Pink one is printed in ABS

I also found this one and ordered one .. just in case .. http://www.hawk-creation.com/index.php?route=product/product&product_id=3057&search=roller
