Looking to adapt a stepper to focuser (SkyWatcher 150 PDS)

[freiform]

Hi,

before re-inventing the wheel; has anyone a hardware adpation/bracket for a stepper to the stock focuser of a Skywatcher 150PDS?

I have a few NEMA14 and 28BYJ-48 flying around and a 3D printer at hand. 

 

Thank you for any suggestions .

Have you had a look a Robert Brown's sourceforge site

Ah, I have, but apparently I had a knot in my brain. I was set on mounting it via the drawtube's base. But of course I can just as well mount it using a bracket screwed to the base of the focusing mechanism itself (where the lockscrew is located). Thanks for making me rethinking it!

if you go down roberts route you will need 4 longer screws to replace the existing one's on the bottom of the focuser M3 I think but please check
