Replacement Focuser wheels for the Vixen 102M. One is the standard size 1.6" (40mm) the other is 3" (75mm) Diameter for fine focus control.
Bit of a unicorn part so probably useless to the vast majority, but to the one person who is going to find this useful…
The sheel is fitted with the angled section for hte focuser shaft. Accepts a shaft diameter of 8.4mm. I use M4 x 10mm hex bolts to hold the wheels. Use variable layer height and hide the seem in on of the grooves for a better finish.
