Easel
thingiverse
This is an easel for small paintings. I was able to use it for 12x12x1/2 thick particle board slab (quite heavy). Parts click in place. Nothing to glue. Easy to disassemble and transport as well. It has a support that maybe useful if one doesn't want to touch the canvas with the top part of the easel. You may have to scale this design 10X to get real dimensions. I think it is due to my CAD software creating STLs in mm.
