I designed this to allow me to wall mount the Anker PowerCore+ units I have whilst they charge so they are on hand and easy to grab when heading out the house. Couldn't find one for this larger Anker battery pack so designed one myself.
This is the second iteration featuring some changes after the initial prototype.
Changes:
The hole in base prevents suction (fit is quite tight) on the battery and also allows the bracket to be mounted in outdoor situations and not have a buildup of rainwater etc. (Obviously battery is not waterproof). Side mounting of the bracket is also possible as tolerances are quite tight so the battery is gripped quite well.
I have printed a couple of these stood on their base with no support and only minimal brim adhesion.
Additional photos when I get a chance.
