I was looking for a reliable way to connect a 20mm and 16mm Preflex pipe, but I couldn’t find a connector that was strong enough for what I needed. So I designed my own.

This connector is optimized to print in the strongest possible orientation, making it durable and practical for real-world use. It uses two zip ties to securely fasten both pipes in place, creating a firm connection without requiring special tools.

I also added a tapered inner cone to help guide wires smoothly through the connector, making cable pulling much easier.

 

Features:

• Connects 20mm to 16mm Preflex pipe
• Strong print orientation for maximum durability
• Secured with two zip ties
• Internal cone shape for easier wire pulling
• Simple and fast to print
