The prompt
Revision to correct the prior overlap: battery is inside cavity upper region, TP4056 inside lower-left region, MAX30102 PCB is mounted on the skin-facing exterior underside and occupies the through-window region below the floor, so it does not collide with the battery. The 75x50 outer footprint with 2mm walls gives 71x46 cavity, not 67x42; this dimensional arithmetic is explicitly corrected. Top STEP remains fixed; mating fit still needs FreeCAD comparison.
