Gridfinity Solum 2.9 inch holder with magnets

I noticed the Solum 2,9 inch E-Ink tags are almost perfectly gridfinity sized, so i designed a simple slider so add your tag to the mighty gridfinity system.

I have decided to add some magnet holes (gridfinity default 6mm diameter / 2 mm thickness), so you can stick it to vertical gridfinity systems or just to any metal object. (Last picture is a magnetic chalkboard btw.)
