GSO 1.25 Focuser Base + Gemini EAF Plate (130mm)

GSO 1.25" EAF-compatible dual-speed Crayford focuser base + mounting plate for a Gemini EAF (adapted for a 130mm Newtonian tube)

I bought this focuser, and the shop offers a choice of two base plates for mounting it to the tube — the one I picked didn't fit my 130mm tube.

So I used the base plate from this model as a starting point and enlarged the hole to clear the focuser's travel. I also had to enlarge the hole on the tube itself.

You'll need:

• 2x 4x5x6 heat-set inserts
• 2x M4x5 screws
• 4x M3 nuts (embed into the base by pausing the print at the right layer)
• 4x M4x10 screws
• 4x M4x80 screws
