retaining pin

This is a simple replacement retaining pin designed for small rod or window blind mechanisms.

I originally lost the original plastic pin that locks the rod connection, so I designed this replacement to fix the mechanism without replacing the entire assembly.

Specifications:
• Diameter: 5 mm
• Length: 15 mm
• Head diameter: 6 mm
• Head thickness: 2 mm

The pin features a head (stopper) to prevent it from sliding through the hole. It can be inserted manually and holds by friction.

Use case:
• Window blind mechanisms
• Rod connectors
• Small mechanical linkages
• General household repairs

Printing recommendations:
• Material: PETG (recommended) or PLA
• Infill: 100%
• Orientation: vertical
• Slight tolerance included for easy insertion

Note:
Depending on your printer tolerance, you may need to slightly adjust the diameter (±0.1 mm).
