Front Wheel Hook - Brompton Folding Bike Replacement Part

Front Wheel Hook

Replacement Part for Brompton Folding Bike

The hook that locks the front wheel to the frame in the folded configuration of my Brompton bike broke. Also I wanted to get some experience with FreeCAD. So I modeled a replacement.

Instructions

• Print in the provided orientation, flat on the side for maximum stability
• I used 4 perimeters and 30% infill, the part will experience considerable mechanical stress.
• Reuse the M5x25 screw and the two metal plates from the original hook.
• Slide a M5 nut in the square cutout to catch the screw.
