HUMN Style Gridit Wallet

I really liked the idea of the HUMN wallet, but the price and design choices kept me from trying it. Then I saw someone's design on Thingiverse:

I designed one similar, but found it too large. Then I thought of the Gridit organizers and designed this one.

Just print 2 of these and use some elastic strapping. Enjoy!
