Whenever I model small parts in CAD, I often struggle with distinguishing between precise millimeter measurements and the flexibility of the filament. Exact precision isn’t always necessary for most models, and it's easy to gauge the size and flexibility required to handle the intended forces.

This gauge is ideal for visualizing both size and flexibility across various measurements and lengths. Currently, these extruded flat boards are set to 50mm. To test flexibility at a shorter length, simply hold at a specific point and apply pressure to observe its flex properties. I always have this tool beside my desktop whenever im 3D modeling.

There are 11 sizes available (all 50mm in length):

• 0.8 mm
• 1.0 mm
• 1.5 mm
• 2.0 mm
• 2.5 mm
• 3.0 mm
• 3.5 mm
• 4.0 mm
• 5.0 mm
• 6.0 mm
• 7.0 mm
