GT2 Toothed Belt Clamp Plate
This belt clamp plate is part of the 'NEMA17 Belt-Drive Camera Slider' kit. The 70 × 24 × 4 mm red plate clamps both ends of the 6 mm GT2 belt against the Quad LM8UU Camera Carriage's belt tab. A 7 mm band of 2.0 mm-pitch ridges (1.0 mm wide, 0.75 mm tall) meshes with the belt teeth so the belt can't slip. Four M3x12 screws pass through 3.4 mm holes on a 35 × 15 mm rectangle into the tab's M3 heat-set inserts. The holes sit above and below the belt band, so no screw goes through the belt.
Quad LM8UU Camera Carriage
This is the sliding camera sled for the 'NEMA17 Belt-Drive Camera Slider' kit. The 90 × 84 × 30 mm carriage rides on two 8 mm rods set 60 mm apart. Four LM8UU bearings (15 × 24 mm) press into two teardropped 15.05 mm through-bores. A hanging belt tab has four M3 heat-set inserts that take the GT2 clamp plate. The deck has a 6.8 × 30 mm slot for a 1/4"-20 camera screw and four M3 heat-set bores on a 40 mm square. It prints deck-down with no supports.
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.
Slider Idler Fork End Block
The far end block of the 'NEMA17 Belt-Drive Camera Slider' kit. The 45 x 84 x 40 mm block holds two 8 mm smooth rods 60 mm apart in 25 mm deep blind sockets. Each rod is locked by an M3 heat-set insert and an M3x8 pinch screw. A 36 x 13.5 mm fork slot houses the 34 mm flanged twin-625 idler drum on a vertical M5x35 axle, with the nut held in a pocket underneath. It prints lying on its outboard face with no supports, and it weighs about 80 cm³ after lightening pockets.
Slider Motor End Block
This is the motor end of the 'NEMA17 Belt-Drive Camera Slider' kit. The 84 x 48 x 40 mm block holds two 8 mm smooth rods 60 mm apart in 25 mm deep blind sockets, each locked by an M3 heat-set insert and an M3x8 pinch screw. A NEMA17 stepper mounts upside down on the 5 mm top plate with four M3x10 screws (31 mm square) and a 22.4 mm pilot hole. Below the plate, a 40 mm wide cavity encloses the GT2 20T pulley and the belt.
