Laser mount for Sky-Watcher finder scope.

thingiverse

This is an easy adapter for attaching a standard green laser to a Sky-Watcher finder scope. The adapter includes an expanding clamp that fits into a recess on the stock finder mount. Proper alignment is achieved with three M4 screws, which require tapping holes after printing. The plastic threads should be sufficiently strong for collimation forces. Two M3 cap head screws 32mm long and two M3 nuts are needed to hold the adapter together and pull the wedge that expands the adapter in the finder holder. This adapter is designed for a laser with a 23mm diameter, but I'm also uploading a Sketchup file so users can modify the design to suit their specific needs. If you're interested in this type of project, you might also want to check out a rotary switch designed specifically for this laser pointer.
