// The reliable option. Its top is a cup that locks onto the collar bottom
// ring. Its bottom is a flat surface that carries the genuine factory Tapo
// base with two screws. It reuses the project camera-mount parameters, so no
// unverified twist-lock geometry is needed.
//
// Bosses hold the base screws. They straddle the central cable hole and leave
// the center open for the RJ45 and DC cables. Each boss rises from the base
// plate to the rim plane, so it prints from the bed.
//
// Print orientation: rim on the bed. The lugs and the latch beam print on the
// bed. No support.
