Netgear M5/M6 cooling stand?

Hi, I have an MR6150 inbound. I will be using this outdoor, and it may be subjected summer temps (Midwest US) and direct sunlight. It looks like the M5 and M6 are basically the same size? Does anyone have a cooling solution they would share? I have looked on Thingiverse and found some things for the M1 (different case), but nothing for the newer hotspots. TIA!
