Description
One-piece add-on ties for O gauge tubular track, designed to twist into place using built-in 7-shaped hooks that grab over the rail flanges.
The tie is printed as one solid piece with the hooks built in, so there are no separate pegs or clips to lose. The two 7-shaped hooks are angled between the rails during installation, then the tie twists into its locked position so the hooks go over the rail flanges.
These are sized to fit the Menards / Lionel style O gauge track I tested with. I printed a handful of them and they installed as expected on my test section.
Features:
Installation is basically:
For the third rail area, it may help to slip one hook over the flange first to create enough clearance for the other hook to fit between the rails.
These were designed from measurements taken from actual track, but stamped metal track can vary a little depending on how the rail/flange is bent. Test fit one first before printing a whole pile.
These are not official Lionel or Menards parts. They are a 3D printed replacement / accessory part designed for hobby use.
Fit may vary slightly depending on your printer, filament, and the exact track section. If the fit is tight, try another section of track first before changing the model. Some stamped track sections have slight variation in the rail/flange bend.
