Shoei SRL2 Cardo Spirit Freecom helmet mount

This is a mount so I could easily fit a Cardo Spirit HD intercom to my Shoei GT Air II motorcycle helmet using the SRL2 standard fitting system.  Shoei helmets are built to take their own intercom system but it's very expensive and I wanted to mount a cheaper Cardo intercom to my helmet but in a minimalist way, without having to use the glue mount (which would have had to sit quite far back on the helmet).  This model should allow a Cardo Spirit or Freecom to be mounted to any of the Shoei helmets that take the SRL2 intercom.

This is a remix of BoA's excellent SRL2 mount for Shoei helmets combined with the Cardo mount of Rodrigo's (Rocha586) on Cults.  Rodrigo very generously gave his permission for this remix to be published here; his model (for a totally different helmet) is on sale there and fits the Cardo Spirit and Freecom lines.  Combining the halves of each model on Fusion360 gave this one.  It works a treat on my helmet, rock solid and exactly what I wanted.  The other models on Printables for Cardo Pactalk seem to use a very different mount so I had to throw this together.

I printed it with ePA-CF 6 and as per BoA's instructions, used mounts on the build surface.  It separates really easily from the supports.  

I've uploaded the stl and the GCODE file.  I normally use tinkercad but it won't import above 25mb and BoA's file was too big, so I had to feel my way with Fusion360 for the first time - apologies if there was a way to have the stl file made a smaller size but it was beyond me!
