19 inch Rack cable management. Under switch version.

It's been a while since i was thinking of dumping my cable panel in the basement rack. It just did not make my cabinet tidy and there was not enough space for the cables too.So i decided to make my own design which seems to work.
It is quite sturdy if you make it with 4 perimeter lines. Infill does not matter at all.

As you may see i got a bit of warping which resulted in not symmetric walls and the two objects did not align that good. Printed a few kilos filament during other prototypes trying to print it without any warping. Nothing helped. Maybe if i have used a bit of glue on the bed but i do not like the mess after using glue. So i printed a simple patch. Fits perfect.
