Until it stopped trading, Magister Militum used to sell black bases - 2mm thick and laser cut, I think, out of some sort of black plastic or acrylic. They arrived with a paper coating on each side.
Does anyone know of another company that does the same sort of thing? I'm looking for 28mm DBA/HOTT-type bases in particular (so 60mm frontage and different depths). Fluid 3D Workshop looks like it does
something similar, though not in those sizes; if I can't find a ready source of 60mm bases, I'll ask if they do custom sizes. But I thought it was worth checking here first in case anyone knows of a source!
The advantages of these bases over MDF are that they make rebasing easier, they are less vulnerable to spilt paintwater, coffee or beer and they won't have any potential for encouraging lead rot (not sure if this is really a concern, but I always coat MDF bases in gesso before basing in any case).
Any pointers gratefully received!
