To desing a good swithch isfor Lego is very dificult. So it would be much better to decide the distance betwen the radiuses after we have a persuading switch system. The most imprtent thig for swithes tht the track distence nad the end of the swithch have to be on round stud. I think it is importatn tdemand for the seith that we have to be able to use it to build multiple track stations. So there are two Pythagorean round number what we can use for switch design: (1) 3,4,5 stud sided triangle with arc of 33,87 deg and (2) 5,12,13, stud sided triangle with arc of 22.62 deg (22,5 deg is acceptabel). If we have such a good switch design it give us the track distance of 9, 10, 12 or 15 stud. Maybe not 12 stud is the best.

It sounds very satisfactory to "increase clutch power". Well done. This dual gauge rail is very exciting. Have you tried flexible filament for flexible rail?

It is a shame that the tracks are one printed parts. It would be much better to print just rails and use simple Lego plates as slipper. A system of rails would be perfect. This way we could build 4-width and 6-width tracks, and we can use 1x8 plate or 2x8 for sleepers as we wish. Do not forget that Adults buying those 3d printed elements and we prefer to build or own track instead of just clicking together some prefabricated element. A system of rails could even help us to make our crossovers, switches and even double slip switches as we wish. I would be extremely excited to build up my own switch. :) I even thinking of to redesign my own switch and double slip switch plans in that spirit.

I suggest you (1) to keep 4 brick width plate and (2) use rectangular grove-tongue of the original Lego monorail track on your plate. (1) If you use 2 brick width plate, we will need a lot of expensive plate to make the path of the wheels. And all the connections of the tiles will increase the resistance of the track. The longer track elements cause less joint and it is increase efficiency. If you print 4 with plate you can print longer track elements (without deffects). (2) If you use rectangular grove-tongue on the end of your track you can connect it with the Lego track without extra connecting ramp or any other stuff. The distance between the grove and the tongue is 2 bricks, so it is fully Lego compatible.
