Puzzle Cube v1.3

thingiverse

Updated Hellraiser inspired puzzle box using my own planetary gearbox core. Using latest modular [gearbox code](https://github.com/tmackay/solid-core-compound-planet) and to remove the "false" alignments which allowed for a partial open. [Assembly video](https://youtu.be/JLJvNn56pJ8) - Jump to the end to see the finished product in action. ["Core" preparation](https://youtu.be/sk70thJSrVc). These are for the previous versions but are mostly applicable. Key takeaways are dial in your printer to avoid "elephant foot" and tolerence to allow gears to print slightly fused - too much and they will stay fused, too little and there will be too much backlash. Give the core a whack on the side with a rubber mallet to free the gears, then use a single edged razor blade to carefully "crack" the ring gears (take care, blood has been shed to bring you this box - a hobby knife is not the right tool, wedging not slicing). Print at 0.2mm (at least the core - it is designed to produce a 1-layer gap between the ring gears and is sensitive to layer height) and separate ring gears with a single edged razor blade or scraper. Print upper and lower parts separately (around 16 hours each, 8 for the core). Ease the core (wider tabs first, careful of orientation and alignment of the narrow tabs) into the end of the "claw", they will need to flex a little. Enable Support Interface at 100%, Touching Buildplate with overhang of 85 degrees for improved finish. This will give a nice solid disk to support the raised dial which can be pried off. Core does not require support. I'd also recommend "breaking in" the core by giving it a few minutes on a drill or Dremel tool to spin the gears (I use a long M5 nut and bolt in the drill chuck). Mark the starting positions with a pencil. They will soon wear in to move freely. If you are having trouble getting the dials to move, a strip cut from a soda can can be used as a shim. Work it in and around the gap. I have attempted to remain faithful to the original design, however it is apparent that multiple on-screen props were used with differing configurations, even some faces mirrored. To this end I have settled on the widely used [HR1 configuration by Xane](http://www.cenobite.com/box/lament/) The Lament configuration - art by [artist064](https://www.deviantart.com/artist064) "The original Lament Configuration was created by [Simon Sayce](https://www.youtube.com/watch?v=OcX2sYlTq2U) for the original Hellraiser movie".
