Customizable End Caps – Text & Symbols

These fully parametric end caps are designed to cleanly finish rods or tubes in modular builds — while also adding clear visual labels and engraved symbols.

Designed in OpenSCAD, this model lets you easily customize:

• rod / tube diameter
• wall thickness and tolerances
• engraved text (e.g. M6, M8, size labels)
• decorative or functional front symbols

Perfect for modular frames, workshop builds, display systems, educational setups, or storage solutions, where clarity and a clean finish matter.

This model is part of my Modular Connectors system, designed for building flexible, scalable structures from simple elements.

Key Features

• Fully parametric OpenSCAD design
• Customizable rod/tube diameter & clearance
• Optional engraved text (size labels, IDs, notes)
• Optional front symbol engraving
• Multiple built-in symbols:
  • heart
  • hexagon
  • spiral
  • snowflake
  • target
  • paw
• Rounded edges for a clean, finished look
• Designed for support-free printing
• Ideal for single-color or multi-color prints

Export Modes

Use export_mode to generate exactly what you need:

• "lid" – full end cap with text & symbol
• "text" – text only (for multi-color workflows)
• "symbol" – symbol only (for multi-color workflows)

This makes it easy to combine parts in slicers.

Recommended Print Settings

• Layer height: 0.2 mm (or finer for crisp text)
• No supports required
• PLA / PETG both work well
• For multi-color: export text/symbol separately and combine in slicer

Customization Tips

• Increase lid_clearance slightly for tight materials (PETG)
• Use bold fonts for smaller text sizes
• Symbols scale cleanly — ideal for visual size coding
• Adjust text_engrave_depth and symbol_engrave_depth for stronger contrast

Multicolor printing in Bambu Studio

1. Export each stl files you created (lid + text or lid + symbol)

2. Load and print in Bambu Studio

1. Import all STL files simultaneously into BambuStudio

   

2. Click “Yes” to “Load these files as a single object with multiple parts?”
3. Assign different filaments to the various parts
4. Slice and print
