This is a grip for the cover of a Creality ld-002r sla printer. I'm sure it will work for a number of other similar printers, e.g. the Elegoo Mars.

I wanted a handle that would allow me to remove and replace the cover with one hand and this is the result. It should print easily with no supports. The CAD design is available from Onshape

It is attached to the top with a strong double-sided tape. I used Gorilla Heavy Duty Double Sided Mounting Tape although there are a number of alternatives. VHB tapes will work fine. Just don't use the weak double sided foam tape. The base is 2 inches wide so 1 inch wide tape will neatly fit.
