A remix of Wradis' excellent Cable Tray Platsa.
I did this to make it more universal and to be able to use it for the electronics in my wife's indoor tropical greenhouse.
You can resize any axis at will and it'll still work; still having a nice snap when fitting lid and bottom together.
I printed this 5 times at 80% width and height with a length of 20 cm to fit my printbed. These 5 bottoms and lids were staggered, with the 5th lid split in 2, to make one long tray of 1 meter without glue.
Settings used: PLA, 0.4 mm nozzle, 0.2 layer height.
The author remixed this model.
Lid corrected (was a tad too wide on one side), removed holes from bottom.
