This puzzle is essentially what Oskar Van Daventer's proportional oh cube (https://www.youtube.com/watch?v=0BitQBOVUTQ) and Christopher Moore's raptor cube (http://twistypuzzles.com/cgi-bin/puzzle.cgi?pkey=5002) would look like as a sphere.
Here is the sticker design you'll need for this puzzle: https://www.dropbox.com/s/cja4i28syxm8cvg/raptor%20ball.DXF?dl=0 which can be used to order from https://oliverstickers.com/index.php?route=product/product&product_id=570 or by sending an email through the contact info on this site. http://www.chewiescustomstickers.com/custom-stickers.html
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.
