AMZ3D Spool wheel for 8mm-9mm rods (or under)

thingiverse

This simple wheel fits like a glove on AMZ3D filament spools. I was fed up with having to print for five hours to complete a spool that would cover the entire width when all I needed were two wheels that fit snugly on each side. It will slip into place tightly. If you're experiencing trouble removing it, just use a flat screwdriver and pry it out slowly. This is a 30-1 hour print depending on your speed. It's solid and doesn't require much plastic. The hole is 10mm in diameter...So I recommend using 8mm rods, but 9mm rods should work too. If you use 10mm rods, you'll have to sand it down to get a snug fit.
