I like the idea and it printed well enough. A little more explanation on how it operates would be nice, but I figured it out after a bit. You may want to go look at the Voron github to see how they design printed parts for future designs. Clever use of rounded edges(try to avoid 90 degree angles on the build-plate because they can tend to warp and lift easier. Part storage needs cutouts to make retrieval easier. I can get the triangles out by poking from the rear, but I cant reach the straightedge.
