UPDATE 2: Based on feedback from beta testers (my brother), it looks like the slope is a little too steep for the cars to easily climb so I stretched it out 30mm so it was a more gradual slope. The half piece is now 160mm long, and the full piece is now 320mm.

UPDATE: Tweaked the original design: increased space in the C-channel area for the track, and increased the clearance under the bridge. Also exported a 1-piece design, if you have a larger printer, and exported left/right pieces for those of us with smaller printers.

This is a simple bridge for the Magic Tracks (and similar compatible sets). If you have a smaller printer, print 4 bridge pieces (2 each left and right) and print 2 of the dove-tail joint pieces. Connect each side to the neighbor with a 1/2" dowel, which is a nice friction fit for me. Not sure what size dowels are available in metric countries, but it would be very easy to use a smaller size and use blue tape to fill the gap. (or model and print a bushing)
