Mag-Lock Impossible Dovetail Box

A print-in-place magnetic illusion puzzle with a reversible locking core.This is my custom reinterpretation of the classic Impossible Dovetail Puzzle, redesigned to be fully self-contained, print-in-place, and powered by a clever magnetic piston lock that never leaves the box.🧩 How It Works (Without Spoiling the Fun)The box prints in three main parts—the base, the middle core, and the lid.Each of these parts includes a mid-print pause just before the magnet cavities are sealed. This lets you drop in a12X3 mm magnet, and then the printer closes the cavity permanently around it for a clean, tamper-proof finish.Inside the middle section is a pair of print-in-place pistons that slide freely but never detach. These pistons are magnetically pulled either down into the base or up into the lid, depending on how the box is oriented.When the piston is pulled upward, it slides into an internal hole in the lid—locking the dovetail seam and preventing the lid from moving.Turn the box the other way
