Multi-Channel Wall Pass-Through

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 holeIntegrated routing for:1× 50 mm water pipe1× 25 mm conduit3× 20 mm conduitsGuided channels ensure proper alignment of pipes and cablesSmall injection holes allow you to apply PU foam for sealing and fixing after installationClean 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:Drill a 68 mm hole through the wall (Use a core drill for a perfect hole)Feed pipes and conduits through the guidesInsert all in
