This is an add-on for the Creality LD-002r resin printer to help drain the resin from the build plate (and model) after a print.
UPDATE: I haven't personally tried it, but others in the comments have said that it also works for the LD-002H. Thanks to those who tried it out!
Other designs have a single angle (rotating around the y-axis). Using one of those I noted that the resin tends to collect on the downward edge, and also inside the "pocket" formed by the bracket. I wanted to be able to tilt the build plate in two axes so that it would drain to a point.
Because having the build plate at two angles moves it closer to the front of the printer, this version also shifts the build plate further towards the back of the printer. That way while it's draining you can (hopefully) put the printer cover back on to protect the resin in the vat. The build plate itself won't hit the printer cover. However, taller prints might, so you'll want to check carefully while putting the printer cover back on.
Also, with this design, part of the build plate is hanging over the printer outside the vat, so there is a chance that resin can drip from the build plate or model onto the printer. To prevent this, I personally slip a folded piece of paper towel under the front of the cover to shield the printer between the vat and the front of the cover (see photos)
This is listed as a remix because I designed it by measuring the other design and borrowing heavily from its style. However, I ended up building it from scratch in Fusion 360. I didn't bother adding a screw hole in the part where the build plate attaches -- in my experience it's stable and doesn't move at all.
