A small travel puzzle with its "print in place" box.
There are many solutions to solve it !
The parts are really esay to print
The box is a little bit tougher. You should have a perfectly calibrated printer.
I printed it in in 0.2mm. If you use slic3r, take care to minimize the parameter "Slice gap closing radius" in the advanced print settings section to something like 0.002 mm.
