And here it is!
After a trip to the $1 store I found some craft foam which is perfect for the padding.
I did a few test cuts to refine the design and I have a working example now that holds an HC-2 securely, but not too tightly.
It slides in and out easily even when connected to the charger and usb cable.
It can be mounted on the fascia so the screen sits above the layout surface or mounted lower so it does not stick up.
There are 3 screw holes that accept number 6 countersunk screws. The foam protects the throttle from the screw heads.
For anyone that wants it to be little tighter an extra pieces of foam behind the throttle at the edges will hold it firmly.
Cost including shipping in the US will be $12, or a 5 Pack for $48
