Creality Space Pi - Bearings

The original design has axles mounted in bearings. The filament spool rolls along the axle, which creates a large rolling resistance. This requires quite a lot of force to unwind the filament from the spool. To reduce resistance, I placed 2 U-bearings on each axle and placed the axle in solid plastic beds. Then the force required for unwinding is minimal and TPU/TPE filament can be used without any problems.
