Here's an external 3D printer enclosure for an SKR Pro 1.1, a Raspberry Pi 3B+ and two QEBDIUL LM2965 buck converters. It features a hinged lid and 3 40x40x10 fans in the rear for cooling.
I have added a case for the SKR 1.3 board and have modified the cover to accommodate the RepRap Discount Full Graphics Smart Display for use with a CR-10 or CR-10S
Updated August 1, 2019: I've added a case to hold the power supply for the CR10 and CR10S underneath the main enclosure with spaces for 2 mosfets to be mounted.

UPDATED: September 17, 2019 - I have split apart the RepRap display mounting from the lids to make it easier to print. Thanks to all who made the suggestion.
Please consider providing a Tip for the Designer as I am on a very limited Social Security income. I do these designs because I have fun doing them and I could use a little money to buy filament to do my test prints. You may also send an Amazon Gift Card to firstname.lastname@example.org
