M4 Level Wheels FAST PRINT ( cr20 , cr10 , Ender 3 )

thingiverse

I was in dire need of some no-frills level wheels that could crank out prints at breakneck speeds. I didn't require anything fancy or elaborate; functionality alone would suffice. If you're looking for wheels with a dash of style, you might want to consider printing something else altogether. A crucial tip: be sure to slap a washer between the spring and the print job to prevent it from chomping through the plastic like a hungry beast.
