Cycloid Joint Output Arm
The 141 mm output link for the 'NEMA17 Cycloidal Joint Actuator' kit. It is 8 mm thick and has a pocketed I-section beam. Its Ø50 hub pad bolts to the carrier's M3 heat-set inserts with 4 M3 screws through Ø3.4 holes on a Ø36 circle, and a Ø8 centre relief hole clears the shaft or bearing. The 32 x 32 tip pad 100 mm out has 4 Ø3.4 holes on a 20 x 20 mm square (MGN12H pattern) for a gripper, sensor or the next joint.
NEMA 17 To MGN12H Carriage Angle Bracket
An L-profile bracket that mounts a NEMA 17 stepper (31 mm square M3 pattern, 22 mm pilot bore) on a 5 mm plate, next to a hollow 40 mm ribbed riser. The riser's 6 mm cap has the MGN12H carriage's 20 x 20 mm M3 pattern, so you can drive a wheel, pulley or leadscrew from a moving rail carriage. Overall size is 48 x 80 x 40 mm, and it prints without supports.
MGN12H To 2020 Cross-Beam Adapter
This adapter plate bolts to an MGN12H rail carriage (four M3 screws on a 20 x 20 mm square, heads counterbored below flush) and holds a 2020 extrusion crosswise in a 20.3 mm locating cradle. Four M5 T-nut bolts go into the extrusion: two up through the floor and two through the cradle walls. It is 64 x 28 x 23 mm and lets you build an X-gantry, camera slider or pick-and-place arm on a linear rail without a machined carriage plate.
Venturi Vacuum Gripper Head
A pick-and-place vacuum head that bolts straight to an MGN12H carriage (20 x 20 mm M3 pattern) and clamps a 4 mm OD PTFE/Bowden vacuum line in a split barrel pinched by a single M3 bolt with a captured nut. A Ø10.5 mm counterbore at the bottom seats a suction-cup collar, and a Ø22 mm scallop with two 4.5 mm zip-tie slots cradles the venturi ejector body alongside. Overall 52.5 x 29 x 52 mm.
608 Joint Robot Arm Link
A 132 mm U-channel arm link with a press-fit 608 bearing pocket (22.05 mm bore, 7.5 mm deep, stepped to a 16 mm clear bore) at each end on 100 mm centres, so two 8 mm shafts or M8 bolts give you a stiff, low-friction structural member for a small robot arm or four-bar linkage. The 4 mm floor carries a 20 × 20 mm M3 clearance pattern (MGN12H carriage or accessory bracket) and both 3 mm webs have 12 × 4 mm zip-tie slots for harness routing; overall 132 × 32 × 15 mm, ~33 cm³.
MGN12H GT2 Belt Clamp Carriage
A 68 × 38 × 5 mm carriage plate that bolts straight onto an MGN12H block (20 × 20 mm M3 pattern, heads recessed in 6.2 mm counterbores) and clamps both ends of a 6 mm GT2 belt on 2 mm-pitch tooth ridges, held by a zip tie through the four 4 × 3 mm slots. Four M3 heat-set bosses (4.0 mm bore, 6 mm deep) on a 38 × 25 mm grid give a flat tool deck for a gantry head, sensor or gripper — the piece a linear-rail axis normally needs but the rail kit never includes.
