VentForge - Parametric Vents & Covers
Version: 2.0.0
VentForge is a customizer for printable vent grilles, vent covers, wall inserts, inspection covers, mesh inserts, and experimental backdraft shutter fronts.
It is useful when a ready-made store grille does not fit your wall opening, duct, workshop vent, cabinet vent, utility room, garage, shed, or custom project.

If VentForge helped you make a custom vent grille that actually fits your wall opening, a Boost would really help this generator reach more makers and support future improvements.
✨ What It Makes
- 🌧️ Rain louver vent grilles
- 🕸️ Printed insect mesh inserts
- 🔲 Solid slicer-infill mesh plates
- 🧰 Inspection / access covers
- ↩️ Experimental backdraft shutter fronts
- 🧱 Wall inserts for rectangular or round openings
- 🔩 Screw-mounted or glue-mounted variants
⚙️ Main Customization
- Rectangular or round wall opening
- Standard size presets for common ducts and masonry shafts
- Functional presets for grille, mesh, cover, shutter, glue mount, and airflow tests
- Frame shapes: rectangle, oval, circle, hexagon, octagon, and flower
- Sharp, rounded, or chamfered rectangle corners
- Screw holes from 2 to 8, with adjustable position
- Louver angle, spacing, count, thickness, and depth
- Printed mesh patterns: square, diamond, slits, crosshatch, or solid
- Separate preview / 3MF colors for base, front, mesh, and clamp
- Normal print layout, exploded assembly preview, or single-part output
🚀 Quick Start
- Measure the real wall opening.
- Choose a Size Preset or enter your own dimensions.
- Choose a Function Preset:
- Rain louver
- Printed mesh
- Slicer-infill mesh
- Inspection cover
- Backdraft shutter
- Airflow-compensated louver
- Glue mount
- Generate, slice, and test fit before printing a large final part.
Presets are starting points. You can keep the preset and disable selected override groups if you want to fine-tune only one part of the design.
🧪 Experimental Features
Some features are intentionally marked experimental:
- Backdraft shutter front - separate moving blades pressed into the front frame.
- Airflow compensation - enlarges the front grille area when louvers or mesh reduce open area.
- Real mosquito mesh holder - for testing a clamped piece of real mesh.
These modes are useful, but fit and movement depend on printer calibration, material, layer height, and selected clearances. Test small before printing large.
🖨️ Print Notes
The default output places parts flat on the bed. Assembly preview keeps the mounted orientation so you can inspect how the parts stack together.
For the printed mesh, the Solid pattern creates a thin plate that can be turned into a slicer-generated mesh by using sparse infill and disabling top and bottom shells.
If the fit is too tight, increase the clearance values before printing a full-size vent.
🌍 Language Versions
The generator includes EN, PL, and DE SCAD versions.

💬 Feedback
If you print it, feedback is welcome. I am especially interested in real fit results, unusual duct sizes, mesh tests, backdraft shutter behavior, and airflow-compensation tests.
