A UV exposure box is an extremely useful piece to make PCBs.
I have searched and found that they are too big and too expensive for my uses. In addition, all the devices require an external power sorce.
Thereupon I decided to build one that fits better on my needs.
My requirements:
-Compact dimensions
-USB charging
-Long battery runtime
-No buttons or knobs
-Very simple use
So I built a box, with which you can exposure up to 184 PCBs on a single charge!
You need to solder, drill a PCB, print the files, programm an Arduino or a ATTiny and
screw everything together.

How I Designed This
I've designed all parts in Google SketchUp.
As a guide, I had all components and especially the glass sheet.
The main body part is cut in half, because my small printer has a plate with only 150 x 150mm.
Then I export the STL files, slice and print them on my printer.
