Looking for options to connect these two foam pieces. There is not enough surface area for glue. Hello! I have this odd custom foam case I made out of tool drawer foam for my keyboard. I needed something a lot slimmer than other options out there so I custom fit it to be the minimum size for my needs. However, it has not held up. There is a section where the two main shelves of it (which do not overlap in the plane of the layers) need to be attached to each-other that I did not design well. The result is the little nubs attached on the side. Unfortunately these aren't holding. One fell off completely the other two separated from the bottom piece of foam. I used contact cement which has generally done me well but I think this joint has too much repeated sheering stress for that to hold. Looking for other options to attach these to each-other that are more physical and not glue. The equivalent of a screw perhaps.…
