update 3/9/2022 - replaced body files with v3. Simplified source models & better fitup as printed. A battery pack for GD-77 & GA-510 style radios using 6 NiMH batteries (or 5 alkaline + 1 dummy). No internal recharging. A model for printing a diy dummy AA is included. A conductor will need to be added for it to be functional. The two halves are joined using 4 3mm cap head screws and thermal threaded inserts. Battery terminals are of this type: https://www.amazon.com/gp/product/B072379C1R Contacts were cut from from nickel battery strip material like this: https://www.amazon.com/gp/product/B07DN8P1MS/ Supports are needed, be sure to specify a support interface that facilitates easy & complete removal. Zvones52o did the heavy lifting with his battery eliminator back piece for the GD-77 ( https://www.thingiverse.com/thing:2742838 ), I used his architecture for the radio attachment layout.
