The file 'Magnet Fidget Utility Knife – 6mm Magnets 3D Printer Model' is (stl) file type, size is 258.5KB.
I really liked the design by cdtsuipo and wanted to print and try it out. Unfortunately, all of the magnets I had were 6mm. And TBH I prefer them a bit larger and stronger.
I redrew it in Onshape.
