M5 Screw Fork Puller For 608 And GT2
A one-piece screw-jack puller. You slide its 8.5 mm fork slot behind a GT2 pulley or 625 bearing on a 5 mm NEMA 17 shaft, or behind a 608 on an 8 mm shaft. Then you turn an M5 bolt through the captured M5 nut (8 mm across flats) against the shaft tip, and it draws the part off squarely without a drift punch. The C-frame is 60 x 46 x 16 mm with a 41 mm inner gap and a 5 mm thin fork for tight motor-face clearance. It prints on its side, so the pulling load runs along the layers instead of across them.
SCARA Forearm With Elbow Pulley
This is the forearm link of the 'NEMA17 Belt-Drive SCARA Drawing Arm' kit, measuring 159 × 44 × 35.5 mm. Its elbow hub carries two 608 bearings (8 x 22 x 7 mm) in 22.05 mm pockets on the 8 mm elbow rod, and it has a printed 60T GT2 pulley for 6 mm belt (37.69 mm tip OD, 44 mm flanges). A belt-anchor pillar holds both belt ends in 2.2 mm tangential slots, and each end wraps around an M3x16 pin screw held by a captured nut. A ribbed beam runs 120 mm out to a 34 x 34 mm tool pad with four M3 heat-set inserts on a 20 mm square and an 18 mm pen hole.
Shoulder 60T Pulley Hub
This rotating shoulder hub is part of the 'NEMA17 Belt-Drive SCARA Drawing Arm' kit. It is a 52 x 44 x 38.5 mm part with a 60T GT2 pulley at the bottom (tip OD 37.69, 8 mm track between 1 mm thick, 44 mm OD flanges) and a 44 mm bolting flange at the top. It runs on two 608 bearings in 22.05 mm pockets (6.5 mm deep at the bottom, 7.2 mm deep at the top) on the base's 8 mm shoulder rod. The top flange takes four M3 heat-set inserts on a 34 mm PCD for the upper arm. A +X lug holds both ends of the open GT2 belt in 2.2 mm slots, each crossed by a 3.4 mm hole for an M3x16 pin screw.
