Description

PDF

Smooth and simple-to-build filament holder, which uses two bearings to ensure good rotation.

Hardware required:

  • 2x 6704-2RS bearings (20x27x4 mm)
  • 1x M8 bolt or threaded rod (the length depends on your required mounting; I used M8x80)

Bearings are inserted on the main body during printing. I recommend inserting pauses in the slicer. To ensure smooth motion and proper fit, please print the test pieces first. The bearing should fit snuggly onto the main body, and the rotating skin should fit snuggly onto the bearing. The M8 bolt should reach as far as possible in the main body to keep it as stiff as possible.
