Today I modded my 3X21C.
I firstly replaced the thermal paste with the Arctic MX-6 that I had laying around.
Eventho I have 3D printer and PTD has shared the STL file for the spacers, instead I added a nut onto each of the original screw to “shorten” it, as it would handle the compression better from being tightened more.
And did some tidying of the solder joints, as well as cleaning the MCPCB and the emitters themself! Since I saw some LED got killed cause of flux residue or debris sitting on the emitter surface.
The only thing different that I did is probably the springs, instead of just wire bypass or double up the springs, I use the spring that I got from Nightwatch as replacements.
The 20mm MCPCB need a little bit of sanding to make the diameter smaller to make it fit, and the springs got soldered onto those MCPCBs, it doesn’t look pretty but seems to do the job really well!
