CNC Spindle Cooling Pump Adapter

This adapter is for the pond pumps supplied with Chinese CNC machines with a water cooled spindle. Mine didn't come with an adapter so I found one for a laser cutter and modified it to suit the smaller tubing diameter.

I have it working in production no problems.

While my print may not be 100% watertight it certainly does the job required.
