Magnet base for 3D Catan pieces with 2x5mm cylindrical magnets

I liked neuport's concept, but those magnets are too expensive. Found ones that are 0.06$ per piece from some chinaman on aliekspress. They are smaller but hold preety well.

Magnets are diametrically(! =radially!) polarized and size 2mm x 5mm. When placed, they must rotate freely so they can snap in in different orientations. Miniguide is in pictures above.

EDIT: For those looking for direct link for the magnets: doesn't exists (yet). Ask this seller: http://www.aliexpress.com/store/138353 for radially magnetized 2 x 5mm magnets, and he will provide it for you.

EDIT2: Added border files. For easier print I combined base with jawongs borders. You have to insert magnets middle print (if you want them). Also added bases separately, if you want to glue them.
