Stackable riser/turntable for resin 3d printer UV curing stations

--edited--
My 3rd iteration of the curing riser is for the Elegoo "Mercury Plus 3" wash and cure station. However, you should be able to scale it a bit to make it work on any curing station with a round turntable. The files are for a 256mm diameter turntable, so scale based on that. 

I recommending printing:
1x v3 base (goes on the turntable)
1x v3 133mm riser (for 2 levels of curing) 
2x v3 87mm riser (for 3 levels of curing) 

The photos of the 3 level risers are actually 97mm, which i think is too much so i created the 87mm.

I don't recommend anyone use v1 ("old") files. 

I printed this in PLA. i don't know the best filament, but white/clear is probably best for reflectivity.
