Rotatable Friction Free Filament Guide 2020 slide-on (608 Bearings)

Based on: https://www.thingiverse.com/thing:2025804

I designed this to be able to print very smooth flex TPU,
My double gear extruder couldn't get enough grip on 85a flex tpu and was constantly losing grip on the filament causing under extrusion.
Works best combined with a spool holder on bearings.
Fits on 2020 aluminium profile.

Reguirements:
2x 608 bearing (22,1x7mm)

Supports = no
Brim = yes (filament guide only)
Resolution = 0,2

No need to reorientate on the build plate.

I also added some wheel guides and pins in different sizes for less calibrated printers.
Wheel guides are optional.
