I have designed better low profile armrests for the IKEA Markus Desk Chair.

I recommend using a lot of perimeters to make them as sturdy as possible. If you can, use Carbon Fiber filament. The second best choice is PETG.

To print the armrests your printer needs at least a 220 x 220 mm buildplate.
