Adapter for secondary mirror

thingiverse

This model was created specifically to accommodate a smaller telescope secondary in its holder due to someone's request. To ensure proper functionality, rotate the design as needed to support the telescope without any additional assistance. For optimal results, printing or painting this design in black is recommended to minimize unwanted reflections. Keep in mind that the provided dimensions refer to the top projection. If measuring the mirror directly, use the smaller axis when laid flat, and apply the same measurement technique to the outside of the model.
