Print-ready 3D models

Robot Joint Harness Dress Clamp

A bolt-on cable dress clamp for the shoulder and elbow joints of printed robot arms, quadrupeds and hexapods: a 180 deg snap-in channel with a fixed 16 mm minimum bend radius parks a service loop so the harness flexes instead of kinking where it crosses the joint. The 9 mm wide channel (tapering to a 7.5 mm snap mouth) takes a typical 6-8 mm servo/encoder bundle, bridge caps capture it at both leg ends, and it mounts with four M3 screws on an 18 x 13 mm pattern. Overall 54.4 x 51.2 x 17 mm with a 20 mm core hole for a tie or driver access.

⚠ Flagged: lifting or tensioned load. Not for safety-critical use without independent engineering review.

Fin Ray Compliant Gripper Finger

A Fin Ray-style compliant gripper finger, 94 mm long × 30 mm deep × 22 mm wide, with a 3 mm contact beam, a 3 mm tapered spine and six 2.6 mm cross ribs, so the face wraps around whatever it touches instead of point-loading it. It bolts to any jaw carrier with two M3 socket screws on a 14 mm spacing through counterbored 3.4 mm holes (5.5 mm heads sink 12 mm deep); the part is mirror-symmetric, so print two identical fingers for a two-jaw gripper.

608 Bearing Swivel Caster Mount

Print-in-place swivel caster for differential-drive robot chassis: the fork prints already captured on the base plate's retaining post and spins 360 degrees, so the third wheel stops scrubbing in turns. A standard 608 bearing (22 x 7 mm) drops between the 8 mm-spaced legs on an 8 mm rod or M8 bolt axle as the hard roller; the 46 x 40 x 5 mm plate bolts up with four M3 clearance holes on a 32 x 28 mm pattern, giving ~39 mm ride height and 21 mm of trail for self-centering.

Print-In-Place Cable Drag Chain

A four-link cable drag chain with an integrated M3 mounting foot, printed fully assembled — no pins, no clips, no post-assembly. Each 32 mm link carries an 11 mm wide x 13 mm tall cable channel and an arc-slot bend limiter that stops the chain dead straight and allows 35 deg of bend, so the top run won't sag. Overall 170 x 29 x 16 mm; the foot takes two M3 screws on a 19 mm spacing.
