The bottom end of Wouxun KG-UV3D battery packs have an intricate set of lugs and ramps:

Wouxun KG-UV3D - battery base

Wouxun KG-UV3D - battery base

Wouxun KB-UV3D - base features

Which requires making something like this:

HT-GPS Case - base plate

HT-GPS Case - base plate

Which attaches to the base of the GPS+Voice case:

HT-GPS Adapter Case - Base view

HT-GPS Adapter Case - Base view

Which came out quite nicely:

HT-GPS Case - base plate

HT-GPS Case - radio base shape

HT-GPS Case - radio base shape

Then slice off the angular parts to suit (the purple objects represent volumes that will be subtracted from the gray part):

HT-GPS Case - base plate - construction

Most of the heavy lifting happened with that version, but this one fits better…
