Couldn't find a spare armrest cover for my older Kinnarps chair, so I made one.

It was a bit of a pain to design a flat part that can fold around a curved armrest and fit the vertical spikes in the frame, but I think it worked out pretty well. It's really easy to print and it fits on a MK3S bed. You probably want your filament to be something flexible, I don't think PLA would be flexible enough. I printed mine in PETG and it seems to do the job just fine. TPU could possibly be better, but didn't test that. I installed mine when the print was still warm but I'm not sure if that makes a difference.
UPDATE: I printed another pair in TPU, and they feel a lot better. I uploaded a new 3MF for the TPU version. It has a more solid body that I filled with 15% gyroid infill. I didn't print any top layer on it. (Picture attached of the PETG and TPU parts)
UPDATE 2: I made a thicker pair to be printed with softer TPU (I think I used 95A). It has a bigger fillet around the edges to make it less sharp. It also has an “infill blocker” that leaves a small slot in the infill when you set the infill on that part to 0%. This fixes a small bulge on the center part of the armrest. I printed this one with just 10% gyroid infill and no top layer,
I used a 0,6mm nozzle with 0,4mm layers but I think anything will work.
