Under-desk cable tray on the print bed
The print preview of the built part. One square is 10 mm.

I want a tray screwed under my desk for the power strip and the cable mess: about 420 mm long, 80 mm wide and 40 mm deep, open at the top, with screw tabs at both ends.

Material
PLA
What the tool did
420 mm is longer than a print bed, so the tool split the tray in two along a dovetail joint, with screw tabs at both ends.
