Mini SC Truck 100% 3D Printed + Working Suspension

🔧 V2.5 Update – Updated suspension tolerances (V2.5)

🔧 V2 Update – Improved Print Stability & Longevity

This update improves print reliability and long-term durability, while keeping the same look and function.

What’s new?

Improved Print Stability
A small, integrated breakaway support increases bed contact for more consistent prints, especially on less-than-perfect build plates.

New Pit Stand (2-in-1 Design)
The support doubles as a Pit Stand after removal, allowing the suspension to relax when not in use.

Updated Suspension Geometry
The suspension is now symmetrical, so axles can be flipped to restore ride height over time.

Tighter Spring Fit
Refined tolerances and added micro retention features improve spring fit.

New Print Profiles

• V2 – Single Color / 4 Color A / 4 Color B with the improvements mentioned above
• Pit Stand (Separate Print)
• V1 Suspension Replacement (Legacy Only)

Note for Existing Prints

If you already printed the V1 truck, you can upgrade it using the V1 suspension profile or print the Pit Stand to help maintain suspension performance over time.

Thanks to everyone for the feedback — it directly helped shape this update.

A palm-size short course truck with real working suspension and rolling wheels.

Designed as a desk fidget toy, the suspension has long, smooth travel just like real off-road race trucks.

Why Print This?

No Hardware
No screws, or glue. 100% 3D printed.
 

No Supports
Engineered to print cleanly without support material.
 

Real Engineering
Functional long-travel suspension that actually “tucks” as the wheels move.
 

Quick Print
About 1.5 hours on the Single color print profile.
 

Ultra-Smooth Rolling Wheels
Low-friction wheel design for satisfying desk driving.
 

Easy Assembly
Snaps together in seconds. See the video for the assembly.
 

The model includes a built-in driver and a detailed short course truck body. Perfect as a desk toy, fidget model, or tiny display truck with realistic suspension movement.

Note:
The suspension is tuned slightly higher to compensate for PLA creep. After a day or so the stance will settle lower, giving the truck a more realistic, aggressive look.

Ensure your build plate is clean! (Soap and warm water works great)
 

Note on Original Engineering

This model features a custom X-link cantilever suspension, developed specifically for this small scale.
 

While I’m thrilled to share this with the community for personal use, please do not reuse or replicate this suspension design directly in other public uploads.
 

Thank you for respecting the time and engineering behind this project.
