Universal C-Clamp / G-Clamp – Heavy Duty 3D Printable Tool (80x40mm)

This is a robust, fully 3D-printable Universal C-Clamp designed for workshop, crafting, and DIY projects. Engineered for maximum strength and ease of printing, this model requires zero supports and features smooth-running threads with a functional swiveling pressure pad. The dimensions are perfectly balanced to handle common workshop tasks while remaining quick and efficient to print.

📐 Technical Dimensions

Main U-Frame: 80mm x 40mm x 30mm

Threaded Screw (with T-Handle): 40mm x 86mm

100% Support-Free: Smart design geometries mean you can print all 3 pieces flat on the bed without any support material.

Precision Threads: Optimized tolerance for a smooth screw mechanism right off the print bed.

Swiveling Pressure Pad: Protects your workpiece and adjusts automatically to irregular surfaces.

Easy-Grip T-Handle: Designed to allow high clamping torque without hurting your hands.

🖨️ Recommended Print Settings

Material: PETG, ABS, or ASA (highly recommended for mechanical strength). PLA can be used for light-duty applications.

Layer Height: 0.2mm (essential for the threads to clear properly).

🔧 Assembly Instructions

Print the 3 parts: Frame, Screw/Handle, and Pad.

Thread the screw through the main frame.

Snap the swiveling pressure pad onto the tip of the screw (a drop of superglue can be used if your tolerances are slightly loose, but it is designed to snap-fit).
