Final pieces of the jigsaw…
Tripod (details over here), laptop plate/shelf and some 50mm wide Velcro (branded, as I was unsure of the stickiness of the unbranded stuff).
The laptop plate came with a sheet of foam and a weird elastic band thing 
The tripod mount for it came with a 3/8" - 1/4" reducer fitted (it just unscrews).
And it was the perfect size for my case too
This caught me out though…
The feet on the case stand taller than the velcro 
I did contemplate taking a stanley to the feet and trying to cut them off… But in the end I simply doubled-up on the velcro, problem solved.
The end result…
