Add me in the Rivnut/PEM nut catagory.
Jay you know our bumpers weren't the quickest to get on/off this year but that was pretty much entirely the design of certain aspects that kept the access down to almost nothing. In the future it would have worked a lot better if we kept the space above open for tools like a ratchet or drill and could have considered wing nuts if we had more space. Keeping all the bumpers mounted on the top side of the robot would have helped too and with a one piece bumper it could have helped reduce the number of mounting points.
For reference we used Rivnuts with a 1/4-20 bolt coming up through the bottom and used non-locking nuts to hold the bumpers on. Often just hand tight due to access but a few received a ratchet.
After doing something similar in 2014 I think it is a good balance of low effort and strong connection between the frame bumpers and frame.
