About this 3D model

Tray to use with 25mm bases that conforms to AoS 3.0 coherency, with each base within 1" of two other bases. Bases are 25mm wide, and with coherency requiring bases to be within 1" (25.4mm) of each other, you're therefore able to be place bases adjacent to them with 0.4mm gap, and still remain in coherency.Inset in the centre are spaces to allow a 16mmx1mm washer to be glued in, allowing magnetised bases to pop on and off easily.
