## 4 - Parameters

If you want to changes the parameters of this design, you can edit the _Freecad_ file [3Dfiles/one_way_valve.FCStd](./3Dfiles/), which is fully parametric, with parameters present in the **Spreadsheet**.

If you want/need to change parameters, we would suggest you play with them and try to understand the impact of each parameters. We will only explain a small selection of important parameters that you are most likely to have to edit.

We will only describe a few parameters that you are most likely to have to change.

### 4.a - Structural parameters

_**wall_thickness** :_ \[_default=2.7mm_\] The wall thickness accross the print (_except for the strap attachment point_). Can be tweeked to make the print either stronger or weaker but lighter and faster to print.

_**snap_fit_clearance** :_ \[_default=0.09mm_\] The clearance between two objects that would fit togeteher with difficulty. Also impact the clearance betwen threads.

### 4.b - Geometrical parameters

_Coming soon !_
