I designed this Xmas decoration for the Vectary and MyMiniFactory Xmas contest.
This gingerbread man is composed of two interlocking parts, in order to have two colors even without having a printer with dual extruders.
A clearance allows an easy fitting. I tested it and it fitted very well, without any additional post-processing.
