Version 1 is simply a widened lens diameter (from 10mm original to 12mm for RCN4). I would recommend this version. It is a very snug fit around the lens.
Version 2 is slightly experimental. It has slots cut into the lens mount to enable the screw mounts on the RC Nano 4 to be pushed further into the canopy. This leaves more space for components such as the VTX antenna to be positioned behind the canopy. However, it arguably weakens the canopy and I have found it to be a looser fit, potentially causing vibrations. I'm looking to improve this model in the future.

The author remixed this model.
I liked the original author's design but the it's made to fit a 10mm diameter lens. The RunCam Nano 4 uses a 12mm lens diameter. I designed this to match the original author's design but using a lens mount widened to 12mm.
