It's true - Kydex may, in fact, be much better. And for this context,
Kydex being 50% more expensive per area of equal-thickness plastic may
save you money in the end, if you can use Kydex that's half the
thickness of ABS.

That would be excellent! Please keep us informed as to your success.
We thought we might have something for a while (one of the knights in
the area had a contact at an injection-molding place, and would do hire
work), but I think it feel through because of the initial costs
involved (I think making the dies involved ran in the $200 range).
Maybe when I see him next week, I'll ask - it may still be a
possibility, and economically feasible if we have enough interest.
