This lock box is a fun variant of my previously released “Spin Release Gift Box” (https://than.gs/m/1185717) but this one is less obviously a gift box and more of a blind puzzle.

I have created this one specifically to be used inside my Sequential Discovery Puzzle Gift Box (GBS1) (https://than.gs/m/1227965) but it can also be used as a stand alone box.

The lid features a mechanism with four floating latches that slide into place. These latches lock the box shut and will only release when centrifugal force pushes them outward simultaneously. Each latch independently prevents the box from being opened, so only by spinning the box can all the latches move into their outward positions, allowing the lid to lift off.

This puzzle box is perfect for hiding small gifts or creating a fun challenge for the recipient. It’s an engaging blend of physics and ingenuity that’s sure to impress!

100% printed - no hardware, fasteners, or adhesives required. No additional support is required.

For the best results, I suggest the following: Material = PLA Nozzle = 0.4mm Layer Height = 0.2mm Line Width = 0.4mm Wall Count = 4 (1.6mm) Top and Bottom Layer Count = 5 Detect Thin Walls = ON Wall Generator = Arachne Infill = 40% (Cubic) Ironing = Not required Brim = Should not be needed Support = None required Print orientation = As per the STL/3MF files.
