use a couple of these to hold my removable tabletop in place. They nicely prevent the table from sliding apart. The cylindrical part has a hole placed off-center to allow for some fine adjustment by turning it after it has been fixed by a screw.

I have only tested it in PETG, but it should also work in ASA, ABS, or nylons. Do NOT print this in PLA as it will lose tension over time.
