Updated Hellraiser ipired puzzle box using my own planetary gearbox core. Using latest modular gearbox code and to remove the "false" alignments which allowed for a partial open. Assembly video - Jump to the end to see the finished product in action. "Core" preparation. These are for the previous veio but are mostly applicable. Key takeaways are dial in your printer to avoid "elephant foot" and tolerence to allow gea 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 gea, then use a single edged razor blade to carefully "crack" the ring gea (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 gea and is seitive to layer height) and separate ring gea with a single edged razor blade or scraper. Print upper and lower parts separately (around 16 hou each, 8 for the core). Ease the core (wider tabs fit, 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 gea (I use a long M5 nut and bolt in the drill chuck). Mark the starting positio 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 configuratio, even some faces mirrored. To this end I have settled on the widely used HR1 configuration by Xane The Lament configuration - art by artist064 "The original Lament Configuration was created by Simon Sayce for the original Hellraiser movie".
