Parametric TPU Washers – Automatic or Manual

Set of fully parametric TPU washers optimized for FDM printing.
This upload includes two separate versions designed for different use cases.

🔹 Version 1 – Automatic Parametric (Dynamic Proportions)

Smart version with automatic scaling based on the selected inner diameter.

Editable Parameters:

• Inner Diameter (ID) - includes automatic +0.5 mm tolerance
• Multiplier (1x, 2x, 3x, 4x…)

Dimensional Logic:

• Thickness = ID × 0,20
• Final Outer Diameter = (ID × 2) × Multiplier

This system maintains consistent mechanical proportions, automatically scaling stiffness and load distribution area relative to the hole size.

Ideal for vibration damping, load spreading, and elastic spacers.

🔹 Version 2 – Manual Parametric (Full Control)

Simplified version without automatic formulas.

User Parameters:

• Inner Diameter (ID) - includes automatic +0.5 mm tolerance
• Outer Diameter (OD)
• Thickness

Designed for users who prefer complete dimensional control.

🧵 Recommended Print Settings

Material: TPU 95A

• 100% infill
• 3–4 perimeters
• 0.2 mm layer height
• Moderate speed for accurate hole sizing

Suitable for light mechanical applications, elastic spacers, and custom on-demand washer production.
