This a balloon mount for Roombas just apply double-stick tape to the bottom of it and slap it on there. Pretty self-explanatory. It can hold 5 balloons max at the moment. I may make some changes later on.
NOTE: If you want to print this use support. I also recommend sanding the edges as it could puncture the balloons.
