The file 'SeeStar S50 Bahtinov For Use OVER Dew Shield 3D Printer Model' is (stl) file type, size is 12.7KB.
This is a remixed Bahtinov that fits over the Dew Shield that I whipped up. My experience has been that the distance of the Bahtinov from the objective lens does not matter, so this not only reduces the chance of scratching the lens, but it makes it easy to manually focus without removing the dew shield.
