Slide-together picture/print/tablet stand

thingiverse

This is a two-piece stand for holding numerous items upright. Circular or rectangular, portrait or landscape orientation should make it do the job! It prints quickly if you omit the bottom and top surfaces like I did; the infill can become an aesthetically pleasing piece itself. In PLA, using a 0.8mm nozzle, 0.3mm layers at 15mm/s with two perimeters takes about two hours per piece, so four hours total. The fit tolerance is zero, so you may need to run some sandpaper or a Stanley blade along the mating surfaces. Mine slots in with a nice click and it's a very sturdy friction fit. When the stand is assembled, the depth that the legs will accept is about 20mm. Deeper frames can still be used, but they'll sit on top of the hooks and will be unstable (see the picture with the thick cross-stitch frame). In landscape orientation, it can hold anything up to A2. In portrait orientation, probably A1 - anything bigger and it will want to tip backwards. Due to the unusual rotation how Fusion 360 outputs STLs - you may need to align the parts to the bed - in Simplify 3D, go to Edit > Place surface on bed.
