Any of the 28mm halftrack crews I have found are too small. As these are essentially markers to show the halftracks are carrying guys, I’m not too obsessed with quality. Enter the 3D printer.
The 3D model is available on thingiverse.
I decided to go headless, so I could use the extra heads I have from the Warlord Plastic Germans. I also went “legless” so they’d be easy to position in the halftracks.
