Before this, the fuse board had 6 hand-written footprints and only 7 of 43 footprints had a 3D model. The new parts library builds footprints and STEP bodies from datasheet numbers, each tied to the page it came from, with a registration check confirming the body sits on the board, pins go through their pads' holes and pin 1 lands on the right pad. After the change, 37 of 43 parts have a body, and the other 6 are waived with reasons.
