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.
