Baby Gate Bumper

Latest in my line of baby gate accessories, apparently:

The square steel tube of the Evenflo baby gate smack against a painted wooden cabinet. This thing snaps onto the square tubes solidly and provides a nice buffer to hopefully keep from damaging the cabinet.

FYI, I designed and built a different version that snapped on and worked great, but it occurred to me it was a choking hazard if my daughter happened to pry it off. I redesigned the part using the "can't fit in a toilet paper tube" criteria, so it ends up being 40mm wide.
