Stop settling for standard 20mm cubes and start testing the dimensions that actually matter for your projects.

This is a Fully Parametric Calibration Cube designed for makers who need absolute precision across all axes. Unlike traditional test models, this cube gives you total control. If you are printing a specific mechanical part, you can set the cube to match your target dimensions exactly to ensure a perfect fit before you start a long print.

Key Features:

• True Parametric Freedom: Independently adjust the length, width, and height. Test your printer's accuracy at 10mm, 50mm, or any custom size.
• Smart Auto-Embossing: The values you input for X, Y, and Z are automatically engraved onto the opposite faces, making it impossible to mix up your test results later.
• Engineered for Accuracy: Features sharp corners and flat faces to make caliper measurements easy and reliable.
• Support-Free Design: Optimized geometry ensures a clean print without any waste or post-processing, giving you a "raw" look at your printer's performance.

Printing & Assembly:

• Filament: Works with all materials (PLA, PETG, ABS, ASA, TPU).
• Print Settings: Use 3 walls and a 15% Gyroid infill for the best dimensional stability.
• Speed: For calibration, it is recommended to print at your "standard" project speed to see how your printer handles real-world conditions.
• Assembly: None! Just slice it with your custom parameters and hit print.
