The file 'Filament Spool Holder 3D Printer Model' is (stl) file type, size is 98.4KB.
Made a filament spool, pretty simple to print since its just one part
I would recommend using tree branch supports and a layer height of 0.28mm
I would also say to scale it up in your slicer by maybe 5 or 10 percent to make sure it comfortably fits your spools.
I used a wall count of 3 and cubic infill (10%) and it printed very fast and easy
