IKEA NÄVLINGE shaft tension collar/stopper

thingiverse

I frequently move my NÄVLINGE around. Particularly the lamp head, swiveling it horizontally, as I move it from lighting my desk to my 3D printer and back. Due to the slightly loose fit of the original product, this means that the lamp head arm tends to slide too freely in the bracket (a diagonal/horizontal movement), and the bracket itself tends to slide too freely up and down the upright lamp rod (purely vertical movement). I got tired of constantly adjusting the lamp to return it to original positioning, often when I didn't really have a second hand to spare. So, I made a tension collar! They're quick to print, easy and fast to "install," and they work really well! There is definitely room for improvement in this design, and I encourage someone to come behind me and do just that! As I only have one of these lamps currently with plans to buy a second, I'm not going to put more time into this. It is fully functional as is and will perform admirably 95% of the time. The other 5% is probably because too much force was used in adjusting the lamp and physics is physics. Adjusting the lamp head rod does require two hands now, but because it stays put, I don't care. I recommend printing three collars for each lamp. One for above and one for below the lamp head arm bracket, and a third for below that bracket on the upright rod. This has worked out great for me. I used the filament already on my printer, but I'm sure it would look much more subtle in a matching color! Vest of luck! I'd love to know if you used it and how well it worked for you, so feel free to leave a comment.
