Laser polar alignment for Skywatcher HEQ5 Telescope mount

A simple holder for the classic laser pointer pen, that can be simply plugged into the polar alignment opening on your Mount, while keeping your polar scope free to fine adjust your alignment.
Simply plug the laser in, activate it by sliding it with the button into the sleeve and rough align the mount towards Polaris. After that verify the position of laser and polaris through the polar scope and fine adjust for good alignment.
That way, even if the laser is off from the center of the axis of the mount by half a degree or something, it is still possible to align fast, because there is no more guessing if the star in your field of view is really Polaris.
Also works well with automatic polar alignment. If the Mount is already pointing pretty well at Polaris at the start of the routine, it takes much less time to achieve really good Alignment.

Polar scope opening diameter 31.5mm
Laser holder diameter 13.7mm
Might fit for some other mounts as well.

Edit:Improved design with ridges for tighter fit at all temperature ranges.
