A basic holder for skeins/spools of yarn. Incorporates a 2 part top piece that requires threaded inserts for easy printing. There is only one size top right now that should be fairly universal, but if you need a different size, please leave a comment (include either dimensions of that you need or the type of yarn that you plan to use it for) and i can upload an update to this thing and i will reply to your comment to let you know. Also uses a R4AZZ bearing to make it spin freely. It can be printed in really any material, but I designed it to print with ABS. It was designed to have the top be a press fit into the bearing. I have included a 3mf file with all 3 parts, Individual STL files for each part oriented for easy printing, and an F3D file. You can use the F3D file to open in Fusion 360 and make any modifications that you like just as long as the license allows.

Materials Required: Inserts: 4x M3x10 threaded inserts (You can use shorter inserts if you wish) https://www.amazon.com/dp/B0CB8KHW7X Bearing: 1x R4AZZ (1/4"x3/4"x9/32") ball bearing https://www.amazon.com/dp/B0824W4SZW Screws: 4x M3x10 (You can use longer screws, up to 16mm) https://www.amazon.com/gp/product/B08L9JL5Q3

Update: I do have an update to this in the works for a more simpler version that only uses a bearing. There will also be compatibility with a 608ZZ bearing as its a more common size. I had used the R4AZZ bearing as i already had some. There will also be a version that won't need any hardware. It won't spin as good, which is why im planning on that one taking longer due to testing. The bearing only version and no hardware version will be their own thing, and not added to this one.
