Geneva Turntable Base Deck
A 150 x 100 x 6 mm ribbed base deck for a stepper-driven Geneva turntable. It takes a NEMA 17 (31 mm M3 pattern, 22 mm pilot) on counterbored holes, with its axis 40 mm from a raised 8 mm rod boss. The boss has an 8.3 mm slip bore and an 11.4 mm inner-race pad so a 608 bearing spins clear of the deck. There are M3 leg holes at the corners.
