Impossible joint

thingiverse

My dad designed this impossible dovetail joint. It prints well with 0.3mm layers down to 0.5 scale. 0.25 works with some manual trimming. Instructions I recommend printing in the default orientation (lengthwise ) - it will make the pieces slide together smoothly due to the grain of the material. If you print the pieces flat they will snap together snugly and be difficult to remove. If you print in the default orientation consider adding a 3mm brim. It's a pretty fun desk gadget when printed at full size.
