Universal Steerer Tube Dummy | STL File
The Universal Steerer Tube Dummy replaces your fork’s steerer tube when the fork is removed, keeping your headset bearings, spacers, and stem perfectly aligned during storage or maintenance.
It prevents loose bearings, collapsing spacer stacks, and dangling brake calipers. This STL package includes two design versions: a fully 3D-printed version with no hardware, and a metal-hardware version for maximum durability.
A Word to the 3D Printing & MTB Community
These designs take time, testing, and real-world bike work to get right. Shipping tools worldwide isn’t great for the planet, if riders can print locally, that’s already a win. Please respect my work: don’t redistribute or sell these files or printed parts without permission. If you’re a shop or workshop and want to sell printed parts legally, a commercial license is available below.
Compatibility
Steerer size: Standard 1-1/8" (28.6 mm)
Headsets: Straight and tapered
Not compatible: Oversized “Overdrive” steerers from older Giant bikes
Overall length: 220 mm
Key Features
- Two versions included: Fully printed version and metal-hardware version.
- Full-length design: 220 mm long, longer than most real steerers.
- Loose-fit tolerance: Slides in easily while holding everything aligned.
- Spacer-friendly profile: Slightly non-round shape prevents spacers from sticking.
- Top clamp system: Locks the spacer stack in place.
- Top-cap compatible: Standard top-cap bolt threads directly into the tip.
- Brake caliper storage: Threaded holes keep caliper bolts safe and organized.
STL File Only (Digital Download)
This is a digital product. You are purchasing the STL files only to print the steerer tube dummy yourself.
No physical product is shipped. A maximum of 3 downloads is allowed per purchase.
Print Specifications
- Nozzle: 0.4 mm
- Layer height: 0.20 mm
- Walls: 4
- Infill: 20% Gyroid

Note: The fully 3D-printed version requires a well-tuned printer for clean, functional printed threads.
Metal Hardware Version — Requirements
The metal-hardware version requires the following standard hardware (not included):
- 3 × M6 nuts
- 1 × M6 × 18 mm socket head screw
To ensure compatibility, the package includes an oversized variant of the nut pockets and bolt grip features. If your hardware is slightly larger than nominal dimensions, it will still fit properly.
