Tiny 52mm Filter Adapter for Svbony SV535

This tiny adapter slides onto the smooth moving front section of the Svbony SV535 lens and adds a standard 52 mm filter thread (M52x0.75), allowing the use of common photographic filters.

The design is intentionally low-profile and lightweight, adding minimal length to the optical path — which is especially useful for astrophotography setups.

The outer ring diameter was sized so a Bahtinov focusing mask can be easily installed and removed without interference. It was designed to fit the Bahtinov mask model that I already use (https://makerworld.com/en/models/2537491-bahtinov-mask-tokina-135mm-f-2-8-m42)

A simple and practical accessory for anyone using the SV535 for astrophotography.
