Quick Connect - Renderly

Açıklama

A durable, multi-part quick connect system for flexible tubing applications. Designed for 3D printing with optimized tolerances and strong locking engagement. Ideal for robotics, pneumatic routing, and DIY engineering projects. Support-free print, PETG recommended for best performance. This Quick Connect Coupler is a compact, modular tube-joining mechanism designed for fast, tool-less connection and disconnection of flexible hoses. The design uses a multi-piece locking system that ensures secure retention while allowing easy release. 🔧 Components Included in 3MF File Main Coupler Body (Male Section) Female Locking Collar Internal Lock Pin / Guide Rod Mount Base (Optional Fixed Version) Tube Insert Channel (Precision Bore) The model is optimized for: Pneumatic lines Water flow systems (low pressure) DIY robotics fluid routing 3D printer filament guide systems Experimental lab prototypes Orientation Guide Print coupler bodies vertically for better circular tolerance. Print locking collar flat side down. No supports required if chamfers are preserved. Enable “Horizontal Expansion -0.05mm” if tolerance is tight. 🔍 Tolerance Notes Designed clearance: 0.20–0.30mm For tighter fit: reduce XY compensation For smoother motion: light sanding + silicone grease 💡 Post Processing Clean inner bore using 4mm drill bit manually (no power). Slight chamfering improves tube insertion. Test fit before pressurized use.
