Parametric detergent/powder measuring cups, customisable using FreeCAD and the included Python script.

These also have an inner ridge to measure an interim volume.

Two sizes are provided - 40ml/27ml for Persil (UK) liquid, and 145ml/80ml for Ariel (UK) powder.

I recommend printing in PETG as PLA isn't very robust for detergents.

Customising in FreeCAD

I'm using FreeCAD 1.0.1, so using an older version may not give good results.

1. Open the FCStd file and the Python script in FreeCAD.
2. With the Python script open, in the top menu, go to Macro and Execute macro - the design parameters window should open.
3. Enter your design parameters and click OK.
4. The parametric cup will appear in the model view.
