608 Pivot Whiffletree Load Equalizer Bar
A 134 mm whiffletree (balance beam) that pivots on a press-fit 608 bearing (22.05 mm pocket, 16 mm through-bore for an 8 mm bolt or rod). It splits one pull into two equal or ratioed pulls for twin cables or tendons, cart or sled traces, or two-point lifts. Three pairs of M4 clearance holes (4.5 mm) sit at 30, 45 and 60 mm from the pivot. Using matched holes gives a 1:1 split, and mixing them gives 1.5:1, 2:1 and other ratios.
Print-In-Place Tendon Thumb
A two-segment robot thumb, 72 mm long, that prints in place. It has a clevis IP joint with a fused 5 mm pin running in a 6 mm bore (0.5 mm clearance) and two 2 mm flexor/extensor tendon channels that end in a tie window at the tip. The root pivots on an M3 bolt through a 3.4 mm clearance hole, so you can add a tendon-driven thumb to a servo or string-pulled robot hand.
Print-In-Place Tendon Finger
A three-segment robot finger that prints already assembled. It has two 5 mm pin knuckles with 0.5 mm clearance, plus flexor and extensor tendon channels (2 mm bores) for fishing line or Dyneema driven by a servo. It is 18 x 14 mm in section and about 104 mm long, and mounts through a 3.4 mm M3 hole at the base.
Print-In-Place Tendon Robot Finger
A 120 mm, three-joint robot finger that prints as one piece with 16 x 16 mm segments. The pin hinges have 0.5 mm clearance, and there are flexor and extensor tendon channels for 1.5 mm cord or fishing line, with a tie-off hole in the tip. It mounts with four M3 screws through a 32 mm wide flange, so a servo or cable spool can curl it into a gripper.
