The design printed without big issues and seems to fit! Still waiting for the metal rods, though. How is your design holding up in daily use? Are you still using it? I'll also print the spacers so I won't have to cut the rods to the exact lenght. Anything in particular I should watch during assembly?
I used the follwing settings (PLA):
0.2mm/layer
shell/top and bottom layer: 1.2mm
infill: 40%
