MiniSkidi Mk3 rear cover w/ exhausts (antenna ducts) and compartment w/ lid

This remix of the MiniSkidis rear cover adds two hollow exhausts that not only make it look like an insect but also are suitable as antenna ducts for a radio controlled version. Additionally I added a compartment as others already have suggested, but with more rounded corners that extend to the sides and a lid on top. The box is in the arms way so they can't be moved back too far (if using a servo its limits can be set accordingly). I suggest printing the exhausts separetly, upright with brim and supports and attach them afterwards. They fitted tightly in my case but glue should do its job if they're too loose. The lid is hold in its place by only gravity and a tight fit. Might be nice to modify so it snaps into place.
