1:32 SCALE BLUETOOTH CONTROLLED CARS
>> 00_PROJECT_SUMMARY
Let's shrink the engineering lab down to a 1:32 scale for a high-octane DIY build. In this project, I'll be 3d printing a custom chassis from the ground up and rigging it with a Bluetooth-enabled control stack
for precision handling via your favorite device.
Looking to ditch the driver? Let's bake in an optional Autonomous Navigation Mode for those who want to experiment with self-driving logic—just keep in mind this "autopilot" upgrade requires
some extra hardware calibration and a bit more code under the hood.

>> 01_HARDWARE
Scan the Hardware Manifest for a complete tactical breakdown of the components powering this build. While these specific parts aren't "hard-coded" requirements for a functional result, they serve as the proven blueprint I used to achieve peak performance. Consider them your verified reference guide. Keep in mind: since this build relies on additive manufacturing, you'll need a 3D printer on standby to hit those exact design tolerances and specifications. Ready to initialize the build? Let’s spool up.
Pro-Tips for the Build
- Interchangeability: If you have favorite servos or chips, feel free to swap them in—just watch your mounting points!
- Print Quality: For a 1:32 scale, I recommend printing layer size to be 0.12mm and I use PLA+ but many filaments will work.
>> 02_3D_PRINTED_PARTS
Initiate the data transfer! Head over to the Development Guide section to pull the source files for all 3D-printable geometries. Utilizing these pre-vetted STLs will streamline your assembly
workflow and ensure your tolerances stay razor-sharp.
Once you've got the functional foundation down, the floor is yours for some creative "over-engineering." Feel free to iterate on the chassis or push the envelope with aesthetic mods—give it some
aerodynamic flair or a custom shell that screams high-performance.
Assembly Directives
- File Origin: Locate the download links in the Development Guide.
- Workflow: Printing the verified files first ensures a "plug-and-play" experience.
- Creative License: I provide the skeletons; you provide the soul. Custom skins and spoilers are highly encouraged.
>> 03_CHASSIS_ASSEMBLY
It's time to transition from digital blueprints to physical assembly. Phase one: Chassis Integration.
Once your printer has finished extruding the core components, consult the Chassis Assembly Prep and initialize your "cold-start."
This visual guide ensures every mounting point is cleared and ready for hardware. For the full play-by-play, fire up the video tutorial below—we’re going deep into the mechanical guts.
We'll be calibrating the gear mesh, locking in the wheel assemblies, and centering the steering rack. By the time the final screw is torqued, we'll have a rolling chassis primed for its electronic nervous system!
