Parametric OpenSCAD clip for securing antenna elements to a boom tube
- Parametric Design: Customizable dimensions for various boom tubes, element sizes, and hardware
- Integrated Parking Slot: Secondary slot to store unused elements at an adjustable angle
- Chamfered Edges: Enhanced structural integrity with streamlined edges
- Mounting Screw: Centered bore for secure boom tube attachment

- Install OpenSCAD
- Adjust parameters in the script
- Render the model (F6)
- Export as STL (File > Export > Export as STL)
- 3D print using rigid filament
- Main Element Slot: Horizontally centered cylindrical cutout
- Parking Slot: Angled secondary cutout for element storage
- Screw Hole: Vertical bore through center for boom attachment
- Symmetry: Mirror operation creates identical chamfers
- Materials: PETG, ABS, or ASA for outdoor durability
- Infill: ≥40% with 4+ perimeters
- Orientation: Print with flat side down (Z-axis parallel to screw hole)
