I’ve been building, collecting, and racing 1/32 slot cars for roundabout ten years now, and I think I’ve seen the future. But let’s take a step back first.

This is a model I just bought of Mark Donohue’s Shelby GT350, made by Revell-Monogram. It’s probably around 4 years old, but it’s a really high quality car. RM’s cars are typically very smooth, and are some of the best looking 1/32s you’ll find.

The drawback to them, however, is that they’re really only competitive with themselves. What I mean is that the only cars you can usefully race a Monogram GT350 against are other Monogram GT350s. Here’s why:


Monogram went authentic with the layout, with a front mounted motor and a driveshaft, which is a bit of a rare setup. You can mess around with them and make it kinda run with a Carrera (it’ll be too quick) or a Scalextric (it’ll be too slow), but there’s no real tuning of this chassis.

Enter Shapeways.

Shapeways is like the Etsy of 3D printing. People upload their designs, Shapeways prints them and sells them. And some geniuses (I use that term unironically) have used that system to solve my GT350's problem.


What is it? To a slot car racer, it’s the answer to to the ultimate question of life, the universe, and everything (50 LaLD points to the first person to get that). This is a chassis for my Monogram GT350 that allows me to install a Slot.it motor pod, and utilize all of the tried and true Slot.it tuning techniques and parts.


Here’s a picture with the pod installed:

With the pod installed, I’ve got great spherical brass bushings for my rear axle, I can install suspension, I can adjust axle heights. This chassis lets me standardize the car’s performance with basically any other make or model of slot car.


Granted, it still won’t be as quick as a Slot.it Group C car, since they’re a lot lower and wider, but I’ll be able to get it to run with Scalextrics and some of the other quicker brands, which is the point.

There’s already quite a few chassis available from Shapeways, and I’m very happy with the quality of the part. And $15 to take a car from unusable to race winner, that’s a pretty good deal to me.
