Very early days yet on this design. A couple of hours of measuring and sketching in Fusion360. Needs some finessing, but the principle is sound.
Given 90% of my printed things are quite short, (keyboards, Mini computer case prototypes and miniature monsters) I can comfortably make a very efficient 90 Degree bed resin drip drainer and keep the cover on!
Most drainers are maybe 20-40 degrees or so!
