Omnicharge 20+ power bank EU/UK mains outlet cover

The Omnicharge 20+ is a great power bank, but it's always bothered me that the 240V socket on the EU/UK version has exposed terminals, meaning it's possible to have exposed live contacts. 
This cover is the first ‘proper’ thing I've designed and made, so it's simple, but it works. 
I've designed it to print with Filamentum Flexfill TPU 98A at a 0.20mm layer height, 100% infill. Hope you get some use out of it!
