I've designed a mounting bracket for my MDR3 with Taku at WK's shop in Toronto.

It can be mounted either on the top or bottom and each circle of holes is designed to hold either a V-mount shoe or any bracket of your choice with a 1/4 20 thread. The V mount shoe can be orientated 4 ways in each of 5 possible spots, allowing for 20 different positions to mount the MDR3 in.
I have no idea of a cost, the prototype will be tested this week but if anyone is interested let me know and I'll discuss prices with Taku later. The V mount shoes that I'm using are from the back of discarded SWIT batteries - they are plastic and I find them very snug. I have about 5 of them, if I'm unable to find the amount needed I'll have to change the hole spacing to a more readily available shoe like the ones from Element Technica.
At any rate if you're interested let me know and I'll look into pricing.
