CubeCell Capsule body STL

I’ve found the STLs for the capsule caps on github (ASR650x-Arduino/3D_Print/HTCC-AC01), but is there one available for the body? I want to make an extension to accommodate a larger battery and still use the clear cap. If there’s an STL with the internal thread I can model an extension piece. Thanks.

try to find a stl for a normal 1,5l cola bottle cap.

Thank you, I’ll try that.
