140 mm Six-Station Index Platter
The 140 mm × 4 mm work platter for the 'NEMA17 Geneva Indexing Turntable' kit. It bolts to the 608 spindle tube with 3x M3x6 bolts through counterbored 3.4 mm holes on a 38 mm PCD. The 24 mm centre hole clears the pointer collar's pad. Six stations sit at r = 50 mm, 60° apart, each with two M3 holes 20 mm apart and a 6 mm locating dimple for mounting fixtures. Six 3 × 3 mm radial ribs on the underside keep it flat. It prints top-face-down, so the work surface, dimples and 1 mm rim chamfer all come out off the bed.
6-Slot Geneva Star Wheel
This is the 6-slot Geneva star wheel for the 'NEMA17 Geneva Indexing Turntable' kit. It is 69.6 mm across and 8 mm thick, with 5.5 mm slots and R17 locking arcs sized for a 40 mm centre distance. The driver's 5 mm steel crank pin turns it in exact 60° steps, and the driver's locking disc holds it still between moves. It spins on a 608 bearing (8 × 22 × 7 mm) pressed into a 22.05 mm seat with a 1.5 mm lip. On top it takes 3 M3 brass heat-set inserts on a 38 mm PCD, which bolt the spindle tube above it.
Geneva Crank Pin Driver
This is the one-piece driver for the 'NEMA17 Geneva Indexing Turntable' kit. It fits on the NEMA 17's 5 mm shaft through a 5.3 mm bore and is held by an M3 set screw with a captured M3 nut. It combines a 50 mm pin disc, which holds a 5 mm x 13 mm steel crank pin at 20 mm radius, with a 33 mm locking disc 9 mm tall. The locking disc has a relief cut into it and holds the 6-slot Geneva wheel still between its 60° steps.
