This Hellraiser themed puzzle box, The Lament Configuration or Lemarchand's box is the latest in a series of previous attempts. What started as a contrived application of a gearbox design has evolved into it's own puzzle with a completely new internal locking mechanism. Pictured in Prusament "Mystic Brown" PLA.
Print in place, fully assembled - optimized for 0.2mm layer height. I've only printed one so far, so still refining the post-processing technique - I might do a video on it later.
Start by running a razor or sharp edge through the outer seams, then pushing the fingers out from the center by hand, working your way around slowly. Crack, crack, crack is the sound of layers de-laminating and moving parts freeing up. Take your time and the box should slide open. Finally free up the dials, I used a hobby knife to wedge in the crack and then slide a sliver of Coke can into the gap and work it around.
Don't be worried if it's a bit tight and binding at first, it will quickly work itself in. Friction creates heat which softens PLA quickly. Just work it back and forth. Warm soapy water may help. Press the heels of your palms firmly on opposite dials to really work them back and forth until they move freely.
As for the locking mechanism, it prints in the "unlocked" position. Without giving too much away, to lock it turn the top dial 180 degrees before turning the bottom dial to engage the "maze" mechanism. Entering the maze is deceptively easy, escaping not so much.
I have included the negative volumes so the design can be applied to your own artwork cubes (eg. Crashjensen's work). I find Tinkercad to be quite adept at complex boolean operations. Import your cube, scaled to 76.2mm, then import the negative, make it a "hole" and combine the two objects. Finally, include the core (might have to translate 38.1mm up).
