Game Pi Zero - back remix

After getting extremely excited about Araymbox's amazing design https://www.thingiverse.com/thing:2823313

I immediately started ordering bits and pieces, unfortunately though, being in Australia, I was unable to get the exact model of battery that he originally used. After a bit of thinking, and with the approval of Araymbox, I set about modifying the back of the case to accomodate:

An 804695 5000maH LIPO battery I got from Aliexpress for $15AUD

A TP4056 Lipo Battery Charger
An MT3608 DC-DC Step up converter.

I then connected all of these, set the MT3608 to output 5V, and everything turned on nicely.

I also didn't really like the writing on the back, so I removed that
