Motor shaft adapter 3mm to 5mm

thingiverse

I used this adapter for my RC Speed Tank by Bryant87. It converts 3.125mm axles to 5mm axles. To get the best fit, start with default print settings and adjust flow as needed. Ideally, there should be no noticeable play. There are three versions available, but I recommend using the adapter_hole version, which worked flawlessly for me. The adapter's stability is impressive, considering my speed tank has powerful motors. So far, I've printed it successfully with PLA without any issues. While material choice doesn't affect performance, be aware of shrinkage when printing with ABS.
