I designed this little enclosure to house a small 5v UPS for my Raspberry Pi's
Its designed for this board
I left space on the one side for the added micro USB port so that i do not have to use a DC power supply with the round plugs. Although it does seem like there should be enough space for those as well.
There is also a small gap in the body where the fitted switch can slot in to make switching it on and off easier. The other gap is for the power out that I uses to directly power the Pi from the GPIO pins.
Hope you find it useful
I printed the lid with the top up since it gave me a better finish.
If you r printer is properly tuned you should be able to print the body as is.
I did flip in my one run to see if i could get better adhesion, but it should be easy to figure out which way works better for you.
