Update 2023-10-02 I modified the screw, made it a bit thinner (-0.1 mm) to compensate for tolerances, I did n to print it myself yet, so when you do please give feedback. Also uploaded the modified Fusion 360 file.
Update 2023-02-05: I modified the thread in the right hand track. Due to mirroring the thread was wrong.
Update 2022-11-24 I modified the screw, to make a better fit. When necessary you can re-cut the thread.

I improved the holding of the blade so it will not fall off when you turn the track up side down.
Also improved the tolerances on the handle/arm.
Made the connecting parts the same height as standard Duplo tracks.
Added a right hand switch base and blade.
All the parts for one right and one left hand switch will just fit on the build plate of a MK3S+. I have provided gcode for each part. The screw and handle needs to be printed twice when you want both the left and right hand switches.
For those interested I added the Fusion 360 file. (Beware I am only an amateur, the design process was quick and dirty….)
