This is a two part (two color) hexagonal medal holder / frame to display your medals neatly on the wall. Due to the hexagonal nature, every amount of medals can be arranged in a symmetrical and nice way. Because hexagons are bestagons!
It requires printing two parts, the base and the frame. Because of two parts, you can make them out of two colors. I used Black for the frame and Gold for the base part and that looks just beautiful. After printing, glue the parts together - I used hot glue and works as a charm. Make sure the orientation of parts for gluing is as you print them - the top part of the frame has a small indent for a nail.
To put it on the wall, all you need is a single, not too big nail. If you plan to put multiple frames on the wall, use the provided tool - it is an equilateral triangle, so you can space the nails equally.
In order to put medal in the frame, feed the medal's ribbon through the topmost hole, then through the bottom one, and finally through the second from the top. Align the medal so it's placed in the middle of the frame, and wrap the rest of the ribbon around inside the frame.
