Attachment to allow connecting Ballanux's helical focuser https://www.printables.com/model/265768-non-rotating-helical-focuser-with-collet-for-hadle for the Hadley telescope to Fantastic Plastic Person's 80mm Refractor https://www.printables.com/model/178990-80mm-refractor-telescope (or any telescope that has the same 57mm spaced m3 screw mount, like the Skywatcher Heritage 130p the original Crayford focuser was designed for.)
Why use this over the recommended 1.25" Crayford focuser? Ballanux's non-rotating focuser doesn't require any additional hardware (just some superglue and electrical tape), so this will save you a trip to AliExpress :)
Note that this might be slightly too long to use with a diagonal. Sorry about your neck.
