Jansen 78.7 mm Tie Link
Tie link for the 'NEMA17 Twin-Motor Strandbeest Walker' kit (print ×8). The same part serves as link c (B-K) and link f (D-F) on every leg. It has two 4.5 mm M4 clearance pivot bores exactly 78.7 mm apart, centre to centre, in 16 mm OD × 6 mm hubs, and a solid flat-bottomed 14 × 5.5 mm bar with 0.8 mm chamfers. It is 94.7 mm long overall, runs at layer L2 on M4x25/M4x30 socket head pins with washers and nylocks, and uses about 6 cm³ of plastic.
Jansen 100 mm Upper Link
Upper link j for the 'NEMA17 Twin-Motor Strandbeest Walker' kit (print ×4). It joins crank pin M to rocker vertex J. The two 4.5 mm M4 pivot bores are exactly 100.0 mm apart, centre to centre. Each sits in a 16 mm OD × 6 mm hub, and the flat-bottomed 14 × 5.5 mm bar is 116 mm long overall, with a 1 mm lightening groove along the top. It runs on M4x35 (M) and M4x25/M4x30 (J) socket head pins with washers and nylocks.
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.
Walker Center Deck Tray
A 150 x 120 mm electronics deck that hangs between a walker robot's side frames. It has four 37 mm drop tabs with M3 clearance holes (3.4 mm), a 20 mm M3 standoff grid, 22 mm battery-strap slots and two 20 x 12 mm rounded wire pass-throughs, so you can mount controllers, a battery and wiring on one flat tray.
Walker Side Frame Plate

It measures 176 x 80 x 6 mm and carries a NEMA17 on its inner face: 31 mm square M3 pattern, counterbored 6.5 mm on the outer face, a 22.4 mm pilot recess and a 16 mm crank-boss hole. It also has the two fixed Jansen leg pivots at ±76 mm, which are 4.5 mm M4 bores with 16 mm thrust bosses, plus eight 4.0 x 5 mm M3 heat-set bores that bolt the centre deck on with M3x10 screws. Lightening slots bring it to about 67 cm³.
