Track Clips for Revell Slot car Track

The Problem

When assembling Revell track, there are two major problems:

  • Pieces fit too tightly, track is hard to fit together
  • Pieces are too loose and come apart easily

Track Pieces are hard to connect

Elbow grease (push harder) is one way to fix this.

Track Pieces Come Apart Too easily

I have designed some track clips that fit in the overlap areas on the underside of the track connection. There are actually 8 different locations (4 pairs) where the tracks join to attach the clips. Here is the underside with two clips pressed into one of the outside locations.

Here is what a single clip looks like (image from Tinkercad)

clip 380

Since the track pieces don’t always fit together the same, I have 6 different gap sizes. You just choose the one that fits best (snug fit).

clip sizes

Code Gap
5 0.350 cm
6 0.360 cm
7 0.370 cm
8 0.380 cm
9 0.390 cm
o 0.400 cm

If you have a 3D printer or know someone who does and can print them for you, here are the STL files that you can use to print them: (all 6 in a zip file)

Using ypur slicer program, you can import all 6 versions and create a set. I usually use 0.2 mm resolution. I have also made projects with 12 or 18 parts at a time.

One thing I have thought about but have not done is make a project with 10 or 20 of the same gap type and print them all in one color. Each size would then be a different color.

If you don't have access to a 3D printer, I can send you some that I have printed. Initially, I would send a batch of 120 (20 of each gap type) for $10, including shipping (the bulk of the cost). Other combinations can be bundled as needed.
