Printed flat on it's back without supports 100% infill and 4 perimeters, 0.2mm layer height.
I used PETG for my print and expect it to last a while.
It fit perfectly for my chair without any modifications to the part after printing.
Forgot to photograph the part before installing it.
– originally I printed using 40% infill, it broke after a few days, next was updated version and printed at max 40mm/s and a bit hotter, hoping for better layer bonding. Will report how long it lasts when it breaks.
