Gridfinity Magnet Hole Generator

Ever find the perfect gridfinity model, only to discover that it doesn't have magnet holes?This kept happening to me, and I don't want to give up my magnets, so I created this tool to automatically generate the magnet holes. Simply input the size of your model then add the generated STL or 3mf geometry to your existing 3D model in Bambu Slicer, center both parts, merge them, then convert the hole cutout geometry to a negative part.
