Couch Legs (longer for Roomba)

thingiverse

Longer couch legs to allow the Roomba to go underneath. Same base and angle as the originals, just extended another 2.5". I used 4 walls and "Support Cubic" pattern - 20% infill. Seems to be holding up just fine after a number of days. Screwed to the couch with 2" screws and washers. We put felt on the bottom of the legs so they don't scratch the floor. I would be a bit more concerned about lateral stress if this were on a carpeted floor where the couch couldn't slide when a child runs and jumps on the couch from the side. For our family and our floor style it is holding up no problems though. And the Roomba cleans underneath now!
