I just received one of
these Tubs Jackson nylon mounts for creating a lower-profile mount for my Cardo Packtalk Edge on my Schuberth E1 adventure helmet. These 3D printed nylon mounts are from the UK and sell for $52. It turns out they are not compatible with the older E1 helmets but do work with the E2, C5, and S2 models. Shipping this little nylon piece back to the UK will cost me nearly $30. So, if you have one of the newer Schuberth helmets, almost any of the newer Cardo intercoms (the list is on the webpage), and $25 you want to part with, I'll sell you the one I ordered instead of returning it to the UK.
