Ribbed Catan Piece Holder (M3 Bolts and Improved Layout)

This is a remix that adds more common mounting hardware and prevents the incorrect layout and insertion of the settlement pieces.

Uses two 25mm M3 Bolts and two M3 Hex Nuts.

The original Model allows for settlement pieces to be inserted upright, leading to players trying to close the box with them in this orientation. The settlement pieces are only slightly to large as shown in the picture below:

The New Design incorporated a Ribbed Structure that does not allow for The Settlement Pieces to be placed in standing upright, and has ribs to indicate the mating of the Settlement Piece Roof to the Rib. See the new Rib Feature Below:
 

There has also been the addition of the M3 bolt compatibility added to this design. The required hardware is two 25mm M3 Bolts and two M3 Hex Nuts. The maximum head size for the M3 Bolt is 5.5mm Diameter X 3.0mm Height. This should be standard on M3 Bolts.

I would have put a latch on, but the tightness of the bolts suffices.
