About this 3D model

Before you print Increase scale to 10x original. I noticed the spools continuously unroll, out of control. So I decided to remove the bearing plate and replace it with this, ever since then, no problems with feed! If you don't have the problem of of them unrolling but still want your spool to stay centered, then buy a longer bolt and it fits right in the top of the spool bearing plate. Good luck printing!
