Neat build but it's a waste to use a 3 element lens on a NUBM44, you're wasting a lot of the power due to clipping off inside the lens assembly. Use a G8 for similar divergence without clipping so much off your beam, you'll see much higher power output (90% transmission G8, 72% transmission 3 element).
 
thank you I will build in 2021 I will soon make some improvements to it

add connector inside for potentiometer

add switch

add connector for switch

change potentiometer position and maybe knob of potentiometer

because i have some unused hole on the host

made aluminium caps for lens

i not have G8 lens

the laser made 6,7W on G2 lens

I will show you some photos
 
You should get about 6.4W with a G8 lens, with similar divergence to the 3 element.
