2.5D Cube Puzzle FabLab
thingiverse
Idea taken from https://thingiverse.com/thing:2469830 Done with inkscape and https://github.com/fablabnbg/inkscape-paths2openscad/releases The gap is set to 0.2mm, which allows most printers to produce a loose fit. You can easily accommodate by adjusting the extruder flow to 110% or 120%. A flow of 120% gives me an extremely strong fit requiring a sturdy workbench and my body weight to assemble. Warning: Do not attempt to solve the puzzle by looking at the photos. To maintain the challenge, the pieces in the photos show a similar but misleading design. Sorry
