Excellent design, great quality. Recommended.
I had previously purchased a 3D model to modify and print to fit my Cardo Freecom 4X to my helmet. However after tweaking it and printing it several times I found it to be a pretty poor fit.
Then after some searching I found mentions of Tubs Jackson and his Cardo mounts. After seeing some good feedback on various social sites I decided to bite the bullet and order one up.
Delivery was pretty quick considering it was the Christmas period, and upon opening I was surprised by how good a quality it felt for being a 3D print. Then came the ultimate test...."does it fit the helmet?". I was a bit tentative as my experience of 3D prints is that anything that needs to flex is often the weak point, so I was happy to see it clipped into place with no issues at all.
Finally found some time to fit the Cardo itself to the helmet and get it wired in, and the Cardo bracket clips onto the Tubs mount with a satisfying click and feels pretty sturdy with minimal flex when pressing the buttons.
I've seen some people comment about these mounts being expensive. Personally, I think they are reasonably priced as you have to factor in the time and skills required to design the parts, as well as the cost of the print itself.
If I was to have one criticism, it would be that for the Freecom mounts, I would have liked the bracket angled upwards slightly at the rear so that the base of the Cardo sat level with the bottom of the helmet, and maybe a small clip to hold the wires, as the wires stick out a bit beneath the bottom of the helmet. Minor niggle though.
Overall, a great design and I would recommend it to anyone wanting to mount a Cardo to their lid.
