Machined parts on a real solid kernel

Machined parts now come from a real solid kernel (Manifold, loaded on first use): a profile plus a feature history of pockets with floor fillets, through slots and drilled, counterbored, chamfered or tapped holes, cut with exact booleans.

The BOSS yoke arms have four pockets with an 8 mm web, a Ø68 H7 bearing seat with a Ø58 shoulder, blind M4 and M3 holes, and a foot drilled and tapped for 8 × M12 and 2 dowels. Their mass comes from the machined volume: 2.99 kg, was 3.33. Inspect and Layers list each feature with the volume it removed. In the split-up view, a dashed line runs from each screw to its hole and through the joint to its nut.
