A simple adaptor that allows you to take the Svbony (non-name brand) Guide scope and attach it onto a Skywatcher tube ring using the screws that comes with both scopes.
Here I've used 2 1/4 inch camera screws to clamp down, I recommend 20% infill but double up and the infill line for increased strength.
Part has been designed to print without supports, you just need to break through the thin layer in the two smaller holes which are used for bridging.
