Statement from Ixion Model Railways Ltd
For those who may be looking I have designed a servo mount for turnout control. im using a 9g servo, levered micro switch with 11mm hole spacing, and .9mm wire to throw the turnout.
its listed on thingiverse as srvo mount for model train turnout. you can also find it listed as servo mount 3B
the direct link is http://www.thingiverse.com/thing:3603598.
the switch I'm using has the number l4 5a 250vac. I'm using this switch because its what I had a bunch of laying around. this could easily be adjusted for other switches. if you would like to adjust for other switches PM me and ill send you a download of my tinkercad file so you can do that.
the servo I'm using is a miuzei sg90 9g micro servo. so again if you have a different servo you'd like to use PM me and send you tinkercad download of the file so you can adjust to fit your servo
as mentioned in one of the comments the pivot may experience excessive wear over time and as per this advice I now plan on drilling the pivot holes in mine and inserting a section of brass tube. I would edit the design to accommodate this but since no two people use exactly the same material I think drilling for the tube is a better choice
I designed this using material I had on hand to experiment with using servos for turnout control. feel free to use as is or to modify for your parts.
my test pieces I printed on my prusa i3 clone using a generic PLA with 15% infill and a speed of 45mm/s. my pieces for installing are printed using most of the same parameters with the exception of changing the infill to 30%
