|Inspired by Dagnall's design to use a servo as point motor.|
The adapter measures only 18mm in height, and is designed for outdoor use.
All used screws should be of stainless steel or brass.
The electronically, cable, connection should be corrosion free.

The servo adapter is a 'one side' design. Select the wanted side before generating the STL file:
SWITCHTYPE=0; // 0=LEFT, 1=RIGHT

The rack can be used for the full 180° servo movement, but for standard LGB/Piko there is only need for 7.5mm which resembles a movement of 120°
The type of rack can be selected in the scad source: THIEL or LGB.
The LGB type hook is positioned 2mm lower on the rack.
The servo pad thickness depends on the used type/brand. (MG servo's are recommended.)
Check the source for setting the right parameter value: (Note: This value includes the 2mm mounting wall.)
SERVOPAD=4.8; // MG90S (Use 4.5 for SG90)
Some hints for printing based on Ender 3V2 and Cura.
For better adhesion, to prevent warping, '3DLac' has been used.
