This project is yet another attempt to make a mobile MMDVM. This time MMDVM and power bank were separated, but power bank is matching the MMDVM enclosure, so they are both could be tighten together.
Check out https://www.thingiverse.com/thing:3649946 for more details since these projects are built up on the same parts and modules.
Use M8x25 bolts to screw up MMDVM enclosure, M8x32 to screw up power bank enclosure and M8x70 to screw up both enclosures together.
