The file 'Quidditch Necklace Holder 3D Printer Model' is (stl) file type, size is 104.7KB.
Daughter wanted something like this that was $80 dollars online. A few 1/4 inch dowels and hours of printing and she's got one for ~10 bucks including plastic and power. Stand will hold up to the 80mm rings. Smaller will likely fit better.
Added a printed jig to help align the posts vertically.
