Roomba i7+ Horns

These horns fit on the Roomba i7+ (and I guess the i7). They stand about 3/4" taller than the little bump on the top and help my Roomba avoid getting stuck under the refrigerator door or the little area under the kitchen cabinets. They don't get in the way of the docking station.

I printed 4 of them laying on their side, with support (although it would probably be fine without support).

I used this double stick tape: https://www.amazon.com/gp/product/B00I4E4NE8

The combination of 4 horns with this tape has been working perfectly for over a month.
