Squeeze Bottle Cap

Design Overview:

• Here are two versions of safety caps for LDPE squeeze bottles.
• These caps are specifically designed for these squeeze bottles, but they might work well for other similar bottles too.

Materials and Fit:

• The caps may not be completely airtight, but they fit snugly on the bottles I have.
• You can scale them slightly to accommodate different bottle sizes.
• You’ve printed the simple version in PLA, but you may choose other materials like PETG or TPU that won’t react with the contents of your squeeze bottles.
• For the version with the captured ring, I recommend printing it in PETG or TPU for added flexibility.

Intended Use:

• I use these squeeze bottles to store homemade airbrush cleaner and airbrush reducer/thinner for my acrylic paints.
• However, avoid using them for volatile solvents.

Specific Versions:

• v1 (Simple Press Fit Cap):
  • Orient the model on the base or top of the cap when placing it on the print bed.
  • PLA works well for this version.
  • Nozzle size: 0.4mm
  • Layer heights: 0.24mm or 0.12mm
• v2 (Press Fit Cap with Captured Ring):
  • Print this version in PETG or TPU for better compliance.
  • The captured ring design helps prevent cap loss.

Remember to adjust the settings based on your specific printer and preferences. Happy 3D printing! 🛠🔍🖨
