Description

This 3D printable wall pass-through system is designed for clean and organized routing of water pipes and electrical conduits through masonry walls.

The design is based on a 68 mm core drill diameter, which matches the standard size for electrical installation boxes in Germany (used for switches and sockets). This makes installation quick and compatible with common tools.

🔧 Features:

  • Designed for a 68 mm core hole
  • Integrated routing for:
    • 1× 50 mm water pipe
    • 1× 25 mm conduit
    • 3× 20 mm conduits
  • Guided channels ensure proper alignment of pipes and cables
  • Small injection holes allow you to apply PU foam for sealing and fixing after installation
  • Clean and professional wall finish

💡 Smart Design:

The guide for the 50 mm water pipe is intentionally offset (not centered).
By combining two guides, you can easily create a slope (gradient) for proper water drainage.

 

 

 

🧱 Installation:

  1. Drill a 68 mm hole through the wall (Use a core drill for a perfect hole)

  2. Feed pipes and conduits through the guides

  3. Insert all in the hole

  4. Seal everything with PU foam via the injection holes
