RD6006 Case in 2 Halves

This is a small case for digital power supply Riden RD6006. My first goal was to design it in 2 halves small enough for my 3D printer (Anycubic Kossel), but I also included reunited design for those who have a bigger printer and could be interested.
Halves should be joined together with four M3 bolts & screws, 2 inside and 2 outside.

Obviously, the main supply cannot be included in this case: I plan to use an external laptop supply with a 5,5mm jack and there is a 10mm hole in the back for that purpose, but I'm still waiting for delivery of the panel connector so it's not on photos.

I have designed open holes for mounting clips to make it easier to dismantle.

I also included a kind of deflector for the fan air flux as it is very close to the bottom, but I'm not sure of efficiency nor usefulness ...
