where to find cheap hosts

Hi all. I was just wondering if anyone could help me out finding a host for my laser heatsink? I bought a laser modual from dtrs laser shop.
I have the 20mm copper laser modual. Where can i find a decent host? I plan to use the OSRAM 450nm 3W PLPT9 450LA-E so I think i may use a single 18650 battery to power it.

thanks all.

Correct me if I'm wrong but those modules are meant more for testing on a platform rather than host building.

See my shop here for host kits: (not available yet, send me a PM)

Or send a pm and I'll custom make a heatsink for ya with this 18650 host:

Cheap is relative. lol

Survival Lasers makes a 20mm DTR module host bundle w. lens: See:

and
20mm DTR module adapter only :

Oh sweet! I got mixed up with the 25mm module
Didn't know these existed
