About this 3D model
Hot air balloon to hang from the ceiling. It also stands on its own but is fragile. It has a ring on the top to attach a rope to the ceiling. The basket is attached to the ring with glue and the ring to the balloon also with glue. The balloon is hollow but when printed it closes at the bottom. I pierced it with a hot screwdriver and cut it with pliers. The layer it makes is very thin and is easily done. You can leave it closed. No supports needed
