I wanted a butterfly style yo-yo with a bearing to allow for better spin.\u003c\/p\u003e\u003cp\u003eI designed this \u003ci\u003emostly\u003c\/i\u003e for a metal 625 bearing, it will certainly work better that way, but if you don't have one handy. There is an included model of a printable 625 bearing that works too. \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eYou'll need a 20-25mm long M3 screw to assemble. There are three different models for the versions, one is opened up to allow a 3mm screw to pass. That side is paired either with a side that uses an M3x5x4 heatset or a side that is undersized to allow the screw to self tap. I am using the heatset versions to allow for more reliable disassembly and reassembly.\u003cbr\u003e\u003cbr\u003eThis ends up being a reasonably light yo-yo so I would print this with plenty of perimeters for when it crashes into something and I would use modifiers to print the outer 6mm or so of the rim with 100% infill to get a little extra inertia. I've included an 3MF that shows how I did that for my prints.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eI also recommend printing with partially bridged counterbores enabled in your slicer, or adding in designed bridges for the counterbores.\u003c\/p\u003e\u003cp\u003eLibre license and FreeCAD files included so you can modify as you see fit, just make sure to share it with the community.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e \u003c\/p\u003e\u003cp\u003eDesign by amd.im on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67434189062448,"sku":null,"price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_2e6bed73-9799-4671-a8ac-34e3a481e8c8.png?v=1785724971","url":"https:\/\/mymadmanlab.com\/products\/butterfly-yo-yo-with-625-bearing","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
