The heat sink is just a simple extension for the 510 and average of about 10MM thick. You could also just change the 510 if you are going to take the chip out.
That would be best case scenario, If I could find one that would fit.
With out looking to unnatural, I'm fussy about how my mods look.
I made 2 3D printed "Gala mods" with SX chips, there dual 18650, very well made prints & can hold up to a 30mm atty. Plus the chip was the most expensive part of the build.
Like I said it's not a total loss for me, But for others it could have relegated this mod to the trash heap

So it's a valid point for top fill atty's, 510 damage does happen.
