Description

Use the newer spool spindle. I beefed up the base so the bolt doesn't sag. The old base broke from sagging when using a 3KG spool.

I wanted a low friction, ball bearing roller to mount to the sides of my XL.

How I print it:

  • Separate to objects.

  • Prusa XL

  • .4 nozzle

  • PLA

  • block supports on the threads

  • 4 perimeters

  • 10 rectilinear infill
