After burning out a 3DR MinimOSD V1.1 from powering it for too long on the ground during testing a while back, I printed an enclosure kit with two large heat sinks for it. 

The 3DR version of MinimOSD V1.1 (with straight video pins) sit in there nicely, it also accommodates some other vendors version 1.2 of the same PCB but with the 90-degree bend video pins. I tried with both, nice fit and keep the chips cool  

I can print one and ship to you including a couple heat sinks, if anyone is interested.

Regards,

Oscar
