3D Scanner magnet marker balls

These fancy 8-faced spheres come in two sizes and can be used for precise scanning using 3D scanners, 6mm cylindrical magnet can hold the marker ball firmly attached to any ferromagnetic surface for quick and easy scanning without the need for sticking markers to the surface.

There are two sizes and two variants to each marker ball, the small ball for 3mm marker with or without a hole for magnet, and the same for the big ball for 6mm markers
The design caters for 6x30mm neodymium cylindrical magnets that need to be press fit into their respective holes, i highly reccomend a vise for this purpose as neodymium magnets are quite brittle so they cant be reliably hammered into place, the tight fit is meant to avoid the need for glue. the odd shape of the top of the ball makes it tricky to hold againt the jaws of the vise so i added little flat-top adapters to first place the balls into then place against the vise, insert the magnet and squeeze until the magnet wont go any deeper.
