This is an insect house in the shape of a mushroom. It has 4 compartments for organic material, one room inside with two doors, and the cap has holes at the bottom so that insects can make their nests in them.
Print the two pieces with usual parameters, spray it with UV resistant lacquer if printed PLA or PETG, glue the cap on the base and attache to a wall/pole using two screws.
