OpenSCAD 2D Plate Profile example

Q: Is this model ready for fabrication?

These examples teach modeling, not manufacturing certification. Verify dimensions, fit, material, strength, and intended use before fabricating any part.

Lesson 3 of 22

2D · preview and export as SVG

Build a planar profile and export SVG before adding any height.

Try changing:

lengthwidthslot_lengthslot_width

Low compile complexity. Planar boolean only; use SVG, not STL.

How this model works

square and circle are 2D shapes. offset rounds the outside perimeter; hull between two circles makes a capsule-shaped cutter. The result has no thickness, so STL is not the right output. Use SVG to inspect the outline; the next lesson extrudes this exact construction.

Make it your own

Increase slot_length without changing slot_width. Identify the maximum safe slot length for the current plate and preserve a wall around it.

Change one parameter at a time and inspect the result. Use the workspace reset action to return to this lesson’s original model.
