Parametric Washers DIN 125 A & Conical (M1 to M90)
Print Profile(2)
Description
š Short Description
This parametric project allows you to instantly generate flat washers according to DIN 125 / ISO 7089 (Form A, without chamfer) and conical (spring / Belleville) washers in any size. Just set the inner diameter, outer diameter, and thickness ā and the 3D model is ready for printing or assembly.
The project covers the full metric thread range from M1 to M90 (including inch sizes), with accurate data from the official DIN 125 table.
š§ Key Features
- Fully parametric: instantly change d1 (inner diameter), d2 (outer diameter), and s (thickness).
- Two geometry types:
- Flat Washer ā classic flat washer (DIN 125 A)
- Conical Washer ā conical / Belleville-type washer (cone angle adjustable)
- Built-in size library from M1 to M90 (taken from the current DIN 125 table).
- Material support: mild steel, zinc-plated, stainless steel A2/A4, brass, polyamide ā choose visualization for your task.
- Easy to use: compatible with Fusion 360, SolidWorks, Blender, Tinkercad (after STL export).
š Standard Size Table (DIN 125 A)
The project includes preset parameters for all common sizes. Examples:
| Nominal thread size | Inner ā (d1), mm | Outer ā (d2), mm | Thickness (s), mm |
|---|---|---|---|
| M1 | 1.1 | 3.0 | 0.3 |
| M3 | 3.2 | 7.0 | 0.5 |
| M6 | 6.4 | 12.0 | 1.6 |
| M10 | 10.5 | 20.0 | 2.0 |
| M20 | 21.0 | 37.0 | 3.0 |
| M30 | 31.0 | 56.0 | 4.0 |
| M42 | 45.0 (or 43.0)* | 78.0 | 8.0 |
| M64 | 70.0 (or 66.0)* | 115.0 | 10.0 |
| M90 | 96.0 (or 93.0)* | 160.0 | 12.0 |
Values in parentheses are the newer ISO dimensions ā also available as parameters.
All data from M1 to M90 and inch sizes (1/8ā³, 1/2ā³, 1ā³, etc.) are preloaded into the project variables.
šļø User Parameters for Adjustment
| Parameter name | Type | Description | Example value |
|---|---|---|---|
| d1 | mm | Inner diameter (clearance for bolt) | 10.5 mm |
| d2 | mm | Outer diameter | 20.0 mm |
| thickness | mm | Flat washer thickness | 2.0 mm |
| type | Dropdown | Flat / Conical | Flat |
| cone_angle | deg | Cone angle (for conical type only) | 12Ā° |
How to use:
Open the parameters, select the required size from the list (M3, M6, M20ā¦) or enter your own values. The model will rebuild automatically.
š§© Example Use Cases
- š 3D printed spacers for M3 to M10 screws.
- š ļø Mechanical assembly in CAD ā accurate standard geometry.
- š© Fastener visualization for engineering documentation.
- āļø Replacing damaged washers in hobby projects (lathes, drones, CNC machines).
š File Formats in the Project
- Parametric source model (e.g., .f3d for Fusion 360 or .SLDPRT)
- Variables table in Excel/CSV (if needed)
- Export to STL, STEP, OBJ ā for printing or rendering
š Standard Compliance Note
Complies with DIN 125 / DIN EN ISO 7089 Form A (ohne Fase) ā flat washers, product grade A, hardness up to 250 HV and above. In the newer ISO standard, some diameters are slightly modified (shown in parentheses), but functional interchangeability is maintained.
*Conical washers are designed on the Belleville spring principle (DIN 6796 / DIN 2093) ā cone angle and height are adjustable.*
