A set of reasonably accurate reproductions of Prince Phillip's military decorations, other than that the center of each medal is replaced with an imported/included STL (I've included an Aperture Science logo from https://www.thingiverse.com/thing:20674 by sicarius and a Bitcoin logo from https://www.thingiverse.com/thing:497827 by vinnivanhood as examples).

Usage

With included designs

> openscad medals.scad -o medals.stl -D 'type=[0-5]' -D 'coin=[1-2]'

eg., to create a military cross medal styled after Prince Philip's Croix de Guerre & Greek War Cross:

> openscad medals.scad -o medals.stl -D 'type=5' -D 'coin=1'

With your design

To use your own designs in the centre of the medals, create (or acquire) an STL centered on the origin, with known diameter and height, then:

> openscad medals.scad -o medals.stl \  -D 'type=[0-5]' -D 'coin=0' \  -D 'coin_custom_file="custom_logo.stl"' \  -D 'coin_custom_logo_dia=50' \  -D 'coin_custom_logo_height=1'

… and a board to hang them on

… and I've included board.scad that the medal ribbons should clip onto.
