This is a simple friction mount for Ikea's Nymane lamp that attaches to their Nordli headboard. You can use a bit of double-sided tape if the lamp does not fit tightly into the housing. Then you just slide it between the headboard and the wall. We use two of them and they stay in place just fine. I had planned to do a little more, but I printed it to test the fit and everything worked perfectly, so I just printed another one and called the project done.
