Maxnomic armrest replacements

As the PU foam of my armrest was crumbling I designed some new armrests similar to the old design. I tested the design in 2 versions. One in TPU 95(Sainsmart) and one in TPU 85A (Ninjatek Ninjaflex). The settings in the 3MF file are based on Ninjaflex TPU as I like that one the most. If you want to print using TPU95 I got the best results when changing the infill from gyroid to aligned rectilinear 15%. I had a couple of failures with Ninjaflex and tried some rear mounted bearing based spool hold
