This is a battery case to mount a TalentCell 12V/6000mAh USB battery (affiliate link: https://www.amazon.com/gp/product/B00ME3ZH7C/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00ME3ZH7C&linkCode=as2&tag=snortimer0a-20&linkId=433046d7601bf1a3f831ab01ca3ccd69 ) under an Electric Eel Wheel Nano by Dreaming Robots (Thingiverse: mribble). You can see the battery lights through one of the top slots.
It requires six 1/2" #8 pan-head screws to clip the battery in and attach it to the Electric Eel Wheel Nano. These ones work: https://www.mcmaster.com/92470a194
You'll need supports, since there are overhangs, and I do recommend printing the main part of it flat with the opening upwards (as in the file). Print the clip flat.
As I'm just now printing the first test of this, the design may change. Feel free to print it and test it for personal use (non-commercial at this point).
