Low-Profile Olympic Barbell Clamp (TPU Grip)
Print Profile(1)
Bill of Materials
Description
A compact, low-profile Olympic barbell clamp designed to provide secure locking while minimizing interference with weight plates. This collar uses a multi-part mechanism with flexible TPU spacers to achieve strong grip and consistent performance during use.
The design prioritizes durability, ease of printing, and structural strength under repeated load.
Features
- Low-profile form factor that does not interfere with plates
- Strong clamping force enhanced by TPU contact surfaces
- Quick-release locking lever mechanism
- Optimized pin orientation for improved structural strength
- Designed to print with minimal supports
Materials
- Rigid components: PLA (functional), PETG or ABS/ASA recommended for durability
- Spacers: TPU (TPU for AMS works well)
Hardware Required
- 4 × M4 nuts
- 4 × M4x25 screws
Printing Notes
- Parts can be printed with little to no supports
- Pins are oriented horizontally to improve strength during operation
- Designed with tight tolerances for a secure fit
It is strongly recommended to bond the Lever Pins to the Base components using super glue. While the parts may friction-fit initially, they can loosen over time and affect clamping performance.
Designed for standard Olympic barbells (50 mm diameter). Fit may vary on non-standard bars.
