Dual 608 Bearing Yaw Joint Pedestal
A pedestal that preloads two 608 bearings (8 x 22 x 7 mm) 36.6 mm apart on a common vertical axis, giving a printed robot-arm shoulder/waist joint the moment stiffness people normally pay $100+ for a cross-roller bearing to get. 44 x 44 mm gusseted flange with four M4 clearance holes on a 32 mm square, 44 mm tall, 19 mm centre bore for an 8 mm shaft plus collars, and a slotted pinch collar with an M3 bolt and captured nut that takes the slop out of the upper press fit.
