PwnCNC Lever Clamp — The Original Low-Profile CNC Workhorse

The PwnCNC Lever Clamp was our very first product back in 2019—and it’s still one of our most beloved. Trusted by thousands of hobbyists and makers, this clamp hasn’t needed a single design change since launch. Why? Because it just works.

⚙️ Key Features

Reversible, Dual-Sided Design
Clamp thinner materials with precision thanks to the rear ledge—perfect for delicate or slim stock. Flip it around for a standard clamping profile.

Tool-Free Adjustment
Each clamp includes a built-in slider mechanism, allowing you to quickly move the fulcrum point without disassembling the clamp. This lets you adapt to different stock sizes with ease, keeping the clamp level and securely in place.

️ Bit-Safe, Low-Profile Design
At less than 6mm tall, this clamp sits low and stays out of your spindle’s way. If a bit does collide, the clamp’s forgiving material ensures your tool remains undamaged—simply replace the clamp and keep carving.

Compact & Lean
Designed for tight setups, the clamp’s narrow footprint makes it ideal for dense layouts and small bed spaces.

Sizing Options

Standard Lever Clamp: 136mm x 30mm x 17mm (under 6mm height above stock)
Mini Lever Clamp: 98mm x 26mm x 17mm (just over 5mm height above stock)

Available in Yellow or Black. Each clamp includes a pre-attached, movable black slider.

A little creativity—we’ve seen these clamps used in every way imaginable!

⚠️ Note: Minor fraying within the slider track is normal and expected due to the 3D printing process. It won’t impact performance.
