The 303 laser, which is easily available for purchase, is thicker than other laser pointer models. As an advantage, it has a safety switch, which allows you to block the activation of the light.
My support for using the laser as a telescope finder came with a ring to allow you to leave the laser on for the desired time without having to keep pressing its switch, but this ring is not wide enough to fit the 303 laser. Therefore, I modeled my own device.
You need to use an M3 screw (preferably knurled to facilitate finger operation) of 15mm (or more), and a nut.
In addition to the main ring, there is a support to be fitted and glued to the end of the screw, which will directly press the laser switch, in a gentle manner and immune to lateral alignment deviations.
This way, you can leave the laser on for as long as you want, or even use the safety switch as the main switch.
