Help finding a laser host kit?

Other Types of Lights Non-LED Lanterns, Incandescent, and HID Lights

I’m after an 18650 laser host. Something like one of these, but without the laser inplace (I already have the laser part from a cat pointer toy).

Anyone know if you can buy these hosts on their own? Thanks.

Might get more response in the Flashlight modding area or the 18650 powered area. Not sure that the query fits very well in a non-LED lights area since the solid state laser is, to me, a form of LED.
