QHY guidescope adapter - 3d print

[wormix]

Has anybody created an adapter like the Modern Astronomy ones to convert a 9x50 finder to guidescope?

I have printer this version;

but the thread requires removal of the front filter on the QHY5L which isn’t ideal. I was going to have a go at creating my own in fusion but wondered if anyone had already done it?

Come up against my first block which is knowing what the thread size is - anyone have any idea?  I’m guessing 26mm x 0.6

 

sound about right?

Figured this out after several trials and error - the threads are (at least for my printer) 50.75mm x0.75 and 25.5mm x 0.75

Printed tonight and gave a quick trial run - works perfectly. Well pleased.
