Twin-625 Flanged Idler Drum
This is the belt-return idler for the 'NEMA17 Belt-Drive Camera Slider' kit. It is a 34 mm dia × 12.5 mm flanged drum with a 26 mm dia × 7 mm smooth face for a 6 mm GT2 belt. Two 625 bearings (5×16×5 mm) press into its 16.05 mm through-bore, one from each end. It turns on the M5x35 axle in the Slider Idler Fork End Block, with one M5 washer on top. The top flange is a 45° chamfer, so it prints standing up with no supports.
