Lament Configuration - Hellraiser Puzzle Box

thingiverse

Functioning Hellraiser Puzzle Box (The Lament configuration - art by artist064) **UPDATED VERSION HERE** Print at 0.2mm (at least the core) and separate ring gears with a sharpened spatula or flat razor blade scraper. Print parts A and B separately, taking around 13 hours each. Ease the core into the end of the "claw", flexing it a little to align the narrow tabs first. Breaking in the core by giving it 5 minutes on a drill or Dremel tool will help spin the gears freely. Similarly, sliding parts might need light sanding or operating back and forth to loosen them up. TinkerCad was used for the final intersection as everything else crashed or made a mess of the mesh. I discovered Inkscape's Flatten Bezziers extension, which improved the artwork significantly. Positive and negative versions are included; personally, I prefer the negative version when slicing for FDM. A rough calculation shows the teeth align every 224.25 turns of the dial (around 3.25 turns of the "slow" gear). Experimenting with hollowing out the cube, but it increases print time (likely due to slower printing of external walls). Solid seems better for FDM. A design flaw in the initial version prevented the "star" configuration; this is fixed in the updated version.
