Parametric DIN9021 Fender Washer Generator M2–M20

This parametric generator creates DIN 9021 large washers (fender washers) from M2 up to M20 with adjustable print clearance and optional inner chamfer for improved screw fit and easier assembly.

Outer diameter and default thickness follow official DIN dimensions to ensure compatibility with standard hardware. The height can also be customized when a spacer or non-standard thickness is required.

Features:

• Full DIN 9021 size range (M2–M20)
• Adjustable print clearance for different materials and printer tolerances
• Optional inner chamfer (one side or both sides)
• Custom height option

These washers are ideal for quick replacements, prototyping, spacers, repairs, or other non-load-critical applications.

If you need standard washers (DIN 125) or additional hardware generators, check my other models.
