Jansen Foot Triangle
Open-truss foot triangle for the 'NEMA17 Twin-Motor Strandbeest Walker' kit (print ×4). It sits in layer L3 of the leg. The pivot centres are F-K 73.4 mm, F-toe 131.4 mm and K-toe 98.0 mm. The two 16 mm OD × 6 mm hubs have 4.5 mm bores for the M4x25 (F) and M4x30 (K) socket head pivot pins. The 14 × 5.5 mm bars are slotted to save weight. The toe is a 22 mm round pad with a 1 mm chamfer and no hole, and it touches the ground. Both faces carry a dimple that marks K.
Jansen Upper Rocker Triangle
An open truss rocker triangle (print ×4) for the 'NEMA17 Twin-Motor Strandbeest Walker' kit. It has three 16 mm OD × 8 mm pivot hubs with 4.5 mm M4 bores at centre distances of B-J 83.0, J-D 80.2 and B-D 111.6 mm, joined by 14 mm wide × 7.5 mm bars. It pivots on the frame's M4x30 screw at B and carries M4x25 pins at J and D. Dimples mark the vertices (one for J, two for D), so you can flip the part for the rear leg or the other side and still tell them apart.
