Have you heard of the Tiny Trak? If not, you should make one! It's so cute!
I got the wheel file from here, it all started here.https://www.facebook.com/groups/181517579149618/
However the original file require glueing the drive wheel to the servo shaft so i made this that has a flat spot, therefore it won't slip and requires no glue.
Step
Print the file
Use a knife the scrap the edge of the middle hole as shown in pic
Cut a flat spot on both side of the servo shaft. START BY CUTTING LITTLE BIT FIRST! then try to push the wheel in, the best is snug fit. You don't want to cut too much and causing too many gaps instead
SCREW the wheel onto the servo
