This profile is optimized for reliable, support-free printing in PETG.The model is designed to print cleanly with no supports required. A brim is recommended to improve bed adhesion, especially on printers prone to edge lift or when printing with PETG.For standard use, 20–30% infill provides a good balance of strength and material usage. If you require a completely solid part for maximum durability and airtight performance, 100% infill can be used.PLA can also be used as an alternative material—just be sure to adjust your print temperatures accordingly. Keep in mind that PETG is recommended for better heat resistance, especially in enclosed or warm environments.Print flat on the build plate for best results.

&nbsp;Window Trickle Vent Adapter Kit – 75 mm Printer Exhaust (Quick Disconnect System)This kit converts a standard window trickle vent into a clean, secure exhaust outlet for your 3D printer. Designed specifically for 75 mm hose systems, it uses a quick‑disconnect coupling so you can attach or remove your exhaust line in seconds without tools. Perfect for users who vent PLA/PETG fumes outdoors and want a tidy, reliable, low‑leakage setup.It can be used without the quick disconnect; just clamp your pipe directly to the vent elbow.<h3>What’s Included</h3><ul><li>Main Trickle‑Vent Adapter – precision‑fitted geometry for common UK window trickle vents</li><li>Quick‑Disconnect Hose Coupler – twist‑lock design for fast attachment and removal</li><li>Retaining Disc / Inner Ring – ensures a tight, rattle‑free fit inside the vent channel</li></ul><h3>Key Features</h3><ul><li>Smooth internal airflow path for reduced back‑pressure</li><li>Strong mechanical joints designed for repeated connect/disconnect cycles</li><li>Print‑friendly geometry with no fragile overhangs</li><li>Optimised for 0.4 mm nozzles and standard PLA/PETG</li><li>Designed for real‑world use: stable, rigid, and tolerant of minor window‑frame variations</li></ul><h3>Printability</h3><ul><li>Supports: enabled, Tree (auto) and tree organic.</li><li>Orientation: as per build blate with flange down to ensure good mating surface.</li><li>Recommended Material: PLA or PETG (PETG preferred for outdoor temperature swings)</li><li>Layer Height: 0.2 mm (can increase to 0.24 to decrease print time by 30 minutes).</li><li>Walls: 2</li><li>Infill: 15%</li><li>Build Plate: Textured PEI recommended for grip and clean underside finish</li></ul><h3>Assembly &amp; Use</h3><ul><li>Attach  the adapter on to the trickle vent opening after the original vent has been removed.</li><li>Attach the quick disconnect fitting to the 75mm exhaust hose using a Jubilee clip/Hose clamp / Worm gear clamp or even a ty-wrap</li><li>Attach your 75 mm hose using the quick‑disconnect coupler</li><li>Twist to lock, twist to release — no clamps, no screws, no fuss</li></ul><h3>Why This Design Works</h3>This adapter solves the common problem of messy, improvised window exhaust setups. The quick‑disconnect system keeps your workspace clean and lets you detach the hose instantly when not printing. The airflow path is tuned for Bambu Lab printers and similar high‑flow systems, ensuring efficient chamber purge and minimal restriction.<a target="_blank" rel="noopener noreferrer ugc" href="https://makerworld.com/en/models/2851844-75mm-trickle-vent-exhaust-kit-90dg-elbow-connector#profileId-3180960">75mm Trickle Vent Exhaust Kit,90dg elbow connector - Free 3D Print Model - MakerWorld</a>
