Enclosure and supports

I designed this slide-in enclosure for the Nintendo Switch (for use with a gooseneck cell phone mount). I wanted it to be slide-in rather than 2-pieces because I didn't want the switch to fall out or to add bulk of screws.

I'm printing with the standard Prusa PLA on an MK3S+.

The first print I made was okay. The second print (at a 90 degree angle from the first - long edge on Y axis) had an issue with the bridging that caused part of the top surface of the print to warp.

For both prints, I used the settings for easy support removal, and I also set the bridging angle to 45 degrees to prevent long drooping bridge strands under the part.

This was the edge that warped. It looked like the bridging infill here warped.

Is there a suggested setting I can make to add extra support under this ledge? I don't care if it looks ugly inside. I just didn't want the surface to look ugly.

 

As a bonus question... If I DID decide to split this model into two halves, how thick would I need to make the vertical struts and tabs for good printing? Is there a rule of thumb for this type of thing? It doesn't have to snap together; I can superglue or heat-weld the two halves if needed.

RE: Enclosure and supports

I would not try and print that thing flat - too many warp inducing surfaces in that orientation.  I'd suggest standing it on end and adding a 5mm brim, with bed-only supports.  A better solution would be adding knock-out panels to the holes when printed on end - that way you won't need supports at all.  With PLA you should see very little warping in the on-end orientation.
