Compact and functional mount designed for FPV builds. Securely holds a 45° SMA connector, perfectly suited for short pigtails. SMA video connector is securely mounted inside a panel cutout, with the nut tightened from the outside. The design ensures a stable fit without requiring a washer or nut on the inner side, making installation quick and convenient. Compatible with both single-nut pigtails and dual-screw flange-mounted connectors.
Also includes a horizontal slot for ELRS or TBS Crossfire antennas, ensuring optimal signal orientation. Features dedicated slots for 2.5 mm-wide cable ties to keep antennas firmly in place without glue or screws (See photos).

Print Settings:

• Supports: Not required
• Nozzle: 0.4 mm
• Layer height: 0.2 mm (recommended)
• Optional: Can be printed at 0.4 mm layer height thanks to optimized design — saves up to 50% print time without compromising basic functionality.
• Orientation: Recommended print position is shown in the last image
• Strength: The chosen orientation ensures high structural strength, as the print lines are aligned in a non-perpendicular way, reducing weak points between layers.
