Note: the new version is here. I recommend that one as it doesn't require a complex clip spring.
This is a battery caddy for the TH-D74A that can hold flat top 18650 LiPo cells.
This model is a work in progress, but fully functional.
I bent the clip spring out of 0.020 piano wire. The contacts are nickel battery welding strips that I trimmed down to size. The contacts are held in place with hot glue, which seems to be sufficient so far.
Included are test prints to make sure they fit with your radio.
The SCAD file is also included if you want to make any adjustments.
