Wheel for 23mm Bearing 23x7

thingiverse

The wheels on my rowing machine just fell apart. So I decided to print new ones using ABS. These fit perfectly onto the 23mm x 7mm bearing and slide right into place after tapping gently with a hammer while holding a board over them. They have stayed securely in place and work great so far. I printed these on my FlashForge Creator Pro without any supports, increasing all outside layers to 7. If you don't keep the print warm during ABS printing, it will warp and be lopsided on the outside. To prevent this, I pad the outside of my printer to trap heat in and they turn out nice and uniform. A little sanding to smooth out any bumps makes them ride smoothly but realistically, they'll wear down to a smooth finish quickly with use.
