This is a slightly smaller core mechanism for my raptor skewb family of puzzles than what I originally included with those puzzles designed to tighten up the those puzzles improving the stability and turning quality on the chance you end up with a puzzle that's a little bit too loose.
This design was created to work with: https://i.materialise.com/en/shop/item/raptor-skewb, and https://i.materialise.com/en/shop/item/raptor-star-skewb.
It is also required in order to build: https://i.materialise.com/en/shop/item/rhombic-raptor-skewb
These are the screws I used for this puzzle. https://www.amazon.com/gp/product/B000NHXOCG/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 This puzzle was also designed to give room for springs which will improve the turning quality. I recommend the springs and washers here https://www.thecubicle.com/products/fangshi-57-54-6mm-hardware
