Replacement Vane 2-Blade Crossbow Bolt 6.5 Inch

If a vane on a crossbow bolt is damaged, the entire bolt is often unusable. This 3D printed vane is intended as a quick, simple, and cost-effective replacement for broken original vanes

I specifically designed it as a replacement for the vanes of 6.5-inch aluminum bolts (total length approx 165 mm) with a Ø 7.5 mm shaft. These bolts are used, for example, for EK Archery Cobra systems or for 3D printed projects like the popular "Adderini" Repeating Slingbow Pistol

Vane Specifications

• Vane Length: 51.35 mm (corresponds to the common 2-inch class)
• Length: 65 mm
• Height: 17.2 mm
• Suitable for Shaft Diameter: 7.5 mm

Key Features

• Precise Fit Design: The curvature on the underside is precisely matched to a 7.5 mm bolt shaft
• Aerodynamic Profile: The shape is based on common hunting and sport vanes
• Cost-Effective Replacement: Simply print a new vane as needed instead of replacing the entire bolt

IMPORTANT SAFETY NOTICE

This component has a direct impact on the flight behavior and safety of the crossbow bolt. The choice of material and print quality are crucial here. A breaking vane can splinter during shooting or lead to an uncontrollable flight of the bolt.
The production and use of these replacement parts are entirely at your own risk!
It is strongly recommended to check the printed vanes before assembly and to test the bolts first on a safe target at a short distance

Print Settings

• Material: I have had good experiences with PLA+
• Orientation: The model must be printed upright, as shown in the pictures
• Build Plate Adhesion: A brim (5-10 mm wide) is absolutely necessary to ensure adhesion to the print plate and prevent tipping during printing
• Support Structure: no supports
• Layer Height: A low layer height (e.g., 0.12 mm or 0.16 mm) is strongly recommended for a smoother, more aerodynamic surface
• Infill: 100% Infill (print solid) is best to maximize stability

Assembly Instructions

1. Completely remove the remnants of the old, broken vane from the bolt shaft
2. Press the new vane onto the shaft at the desired position
3. Done!
