I broke my arm rests on my chair and didn't feel like forking out for a whole chair

Originally I was going to print the top of the arm in TPU however I decided to do the padding myself, hence I split the top half into a mid plate and the top so you can do either.

I printed these out of PLA+, 6 walls(6 was overkill), 10% infill face down on the bed with support and they feel rock solid and still do after 2 years. printed on a Ender 5 Plus.

I added the step file so you can adjust it to suit your chair and/or printer
