Creality LD-001 mini platform

I made a version of the small platform for use a with a smaller trough in the DLP resin printer Creality LD-001. My old filament printer is a b*tch though, so I havent tried my warped print that came out (my orange pic). And you need a small resin vat as well, with a fep-film and ... too much to do! :)

This gave me the idea to build the platform: https://www.thingiverse.com/thing:2946700

This platform is 60x60 mm big.
My design has slots for nuts, to assemble the too parts. Hammer 4 nuts in the slots, align them with the printed holes and stick screws through the slits/holes and it should work like the Creality design when you zero the platform and tighten the screws.

It probably needs a sheet of something like frosted glass or metal for the printing surface.
