I printed a copy of Oskar Van Deventer's “Screw Burr” and had an idea for this variation. This is not a difficult puzzle, but precise alignment is needed to assemble the pieces. If it is not going together smoothly most likely some piece adjustment is needed.
Print one copy of each piece (I use 6 different colors). In a vertical orientation the pieces do not require supports but can come off the build plate. I use a 4 mm brim to ensure the pieces stay attached.
