The prompt
Separate bottom shell for WearCare wristband. Intended to mate with user-provided top enclosure STEP; external footprint target 75 x 50 mm. Internal layout includes LiPo compartment, TP4056 board standoff region, MAX30102 skin-facing optical aperture/holder, and two horizontal magnetic pogo-contact bores at one short side edge. This is a preliminary parametric shell: verify against exact purchased parts and top enclosure in FreeCAD before printing.
