That’ll do it - and after you have used your playing pieces for a while, you’ll see if you need to spray a new layer of matt varnish.
2-3 layers - each layer thinly sprayed - and dry 24 hours between each layer.
You units will last a lifetime:+1:
I have had a 3D printer hobbyist CAD design a new BB playing piece and a new DD playing piece.
The BB is based on the WW1 UK Iron Duke modified for appearance. It is, certainly, better looking than the original BB design. Additionally, I (we) used a depiction of a WW1 US 4 stacker DD to make a modified DD playing piece for A&A WW1. The rationale that the Sub replaces the need for a DD just doesn’t ‘cut it’ (make sense). Most of the colour filaments used to 3D print these units are a good match to the original playing piece colours. I will post pictures of these as I have assistance doing so.
