Sliding Bearing Gear 3D print model

This is a sliding bearing gear for telescope, robotic arm or any mechanism that needs controlled rotation around Z axis (mainly Z, as load distributes evenly). Gear ratio 1:6 for Nema17 motor, and 1:5 for Nema23 motor.

3D-print with 0.8 mm print-head:

• 2xD-SBG_IgusRing12: Iglidur-L170/180PF, infill 100 %.
• all other parts: PC, infill 40-60 %. Thread D-SBG_Moving Inner Ring1_wGear with M3 and assemble using 8xM3x12. Use 6xM3(M4)x30 and 2xM3(M4)x40 to fix D-SBG_Fixed Outer Ring to table together with D-SBG_Motor Holder_NEMA17 or D-SBG_Motor Holder_NEMA23.

Fixing to table: D192 mm, fixing to arm/mechanism: D168 mm.

Works like charm!:)
