Form 3 challenge: printable roller holder

My warrantee is about to expire and it’s got me thinking: wouldn’t it be nice to have a printable roller holder?

I’ve gone through two already. Replacements from Formlabs cost $80. So perhaps it would be smart to create a printable one, and one could transfer the glass, rollers and retaining-plate to the print out.

What would be the best resin to use for the print? I imagine you would want something that it smooth and dark. So something like a dark “durable” resin, if it existed. I imagine you would want it to be dark to absorb as much stray UV light as possible, but perhaps durable (as it is, in white) would be fine. And you want it to be smooth to avoid damaging the resin tray.
