I made this mechanism while building a custom wall track for Hot Wheels 1/64th scale diecast cars. It allows a single car to drop to a track below and continue in the reversed direction. Included are the core mechanism (lever, pin, and bracket) and bump stops that attach to the track pieces. There is also an end stop to catch the car at the end. All pieces print without supports in default orientation.
The lever uses an adjustable counterweight for returning to initial position and slowing descent. For me the sweet spot was putting an additional 15 to 20 grams in the little bucket. Assembly is pretty straightforward. Make sure that the lever can spin freely on the pin. For me it required a small amount of sanding/filing to remove the seam on pin and minor droop from bridging in the lever's hole.
This offset from the wall for this lever is consistent with an included mount for Hot Wheels track pieces. The mount and mechanism work off a wall to track center distance of 33mm. For the reverse direction of the example shown, no mirroring of parts is necessary. There is plenty of clearance between the wall and track for it to still work correctly. Feel Free to make your own adjustments as needed.
