About this 3D model

I printed some Xmas magnets which used a 20mm x 3mm magnet. I only had 10mm x 2mm magnets to hand so designed an adapter to amend the size and figured i would upload in case anybody else needs something similar. I may do other sizes if people need them but if you use the included 3mf file this will print with nice tight tolerances that can be pressed in with a little force so need for glue of any kind.
