The 303 and 403 laser pen, which is easily available for purchase, is thicker than other laser pointer models. As an advantage, it has a safety key switch, which allows you to block the activation of the light.
My laser mount 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 or 403 laser. Therefore, I modeled my own device.
I have one 303 and one 403 laser pointers, and they doesn't share the same dimensions, being 403 a little thicker. Check both files before download.
You need to use an M3 screw (preferably knurled to facilitate finger operation) of at least 15mm (or more), and a nut.
In addition to the main ring, there is a tip 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.
