A Workbench That Refuses to Be Guessed At
A 3D-printed electronics bench — DIN rail, deck ladder, clip-on modules — built under one rule: never print a part until every fit it depends on has passed on something smaller. The interesting half isn't the bench, it's the apparatus around it. Parametric CAD writes its own Bambu Studio projects with per-part wall and infill regimes baked in, a mesh-level assembly simulator rehearses the build before any plastic is spent, and the numbers that decide the design are tapped into iPad sheets at the printer that save straight to disk and work the constant out for you. 525 g of plastic across ten staged plates, of which 146 g is gauges that never leave the drawer.
The build plan is ten plates, ordered so that every plate proves the fits the next one depends on. A 3 g coupon protects an 87 g ladder. The first plate is 7 g of TPU whose only job is to reveal how much this printer over-extrudes, because that one number propagates into every pocketed part in the design.
