As the Crystalsky Ultra is pretty heavy I found it fatigued my old hands after a while. I did a search on the Internet and looked at available commercial items and to be honest most was heavy, over-complicated oriental kak, resembling medieval torture instruments.
So it was to the drawing board...
This is my prototype of which is made from 1 A4 sheet Black 5mm foam board 10*40mm aluminium tube and a stainless steel 8*15mm ferrrel. 1 2.5mm split tension pin and 2*22m split rings.
I was going to use carbon fibre tube but the difference in weight is negligible along with the acrylic sheet to be used in phase 2.
The whole thing weighs in at 54g.
Phase 2 will be made out of 3mm acrylic sheet the board is slotted to allow the 3 items to be slotted together thus laying flat.
I had to design it so that your hands were unimpeded underneath the controller and also giving you quick access the screen.
This is why the support beam is 40mm wide. It seems to work great and also the tray holds the unit 70mm away from your stomach preventing the CS cable being knocked and at the same time giving you a better viewing angle.
Also the C of G is central so all the load is on the neck strap and none on your hands. At this stage I have not designed hand rests into it but that may be an option if I needed.
Here are a few pictures...
