This is my version of the storage tray. I use the 175 mm width version but the legs of my machine are slightly bended outward. 170 mm should work for others.
I printed in Polymaker Polyterra Charcoal Black PLA on my X1 Carbon in 0.20 mm (0.40 nozzle) with 15% infill and 2 walls.
The author remixed this model.
