jayrob makes one for the MXDL flashlight only and it fits AixiZ or meridith for $22 shipped
if you are talking about a heatsink inside an AixiZ module. you could unscrew the cap off and put a straw all the way through the hole, melt some soda cans and pours them inside the housing. let it cool and there ya go! heatsinked AixiZ module with room for wires. maybe neither of these are what you are asking for, if so, sorry
