# YAPP Box Settings
There are a view settings that the YAPPgenerator needs, to create your perfect project box.\
From Top to Bottom of the **`YAPP_template.scad`** file:
```
//-- which part(s) do you want to print?
printBaseShell = true;
printLidShell = true;
printSwitchExtenders = true;
```
**`printBaseShell`**`:` if `true` will print (generate) the **base** of the projectbox and if **`printLidShell`** is `true` the **lid** will be printed. **printSwitchExtenders** controls whether or not switch extenders are printed.
```
//-- pcb dimensions -- very important!!!
pcbLength = 150; // Front to back
pcbWidth = 100; // Side to side
pcbThickness = 1.6;
```
These `pcb-variables` are the reference for most of the other measurements!
```
//-- padding between pcb and inside wall
paddingFront = 15;
paddingBack = 8;
paddingRight = 12;
paddingLeft = 5;
```
With the `paddingFields` you define the space between the PCB and the (inside!) walls of your projectbox.
```
//-- Edit these parameters for your own box
wallThickness = 2.4;
basePlaneThickness = 4.0;
lidPlaneThickness = 1.2;
```
**`wallThickness`** determines the thickness of the standing walls. **`basePlaneThickness`** and **`lidPlaneThickness`** respectively determines the thickness of the base plane and the lid plane.
```
//-- total height inside = baseWallHeight + lidWallHeight
//-- 35.0 = 15 + 20
//-- total height outside = total-height-inside
//-- + basePlaneThickness + lidPlaneThickness
//-- 41.2 = 35 + 2.0 + 4.2
baseWallHeight = 15;
lidWallHeight = 20;
```
```
//-- ridge where base and lid off box can overlap
//-- Make sure this isn't less than lidWallHeight
ridgeHeight = 4;
ridgeSlack = 0.2;
//-- the radius of all outside edges and corners
roundRadius = 3.0;
```
**`ridgeHeight`** is the height of the overlapping edges that centers the lid nicely on the base.\
\&#xNAN;**`ridgeSlack`** makes some room between the lid-ridge and the base-ridge so they snap nicely in each other.\
\&#xNAN;**`roundRadius`** is the diameter with which all edges are rounded.
```
//-- How much the PCB needs to be raised from the base
//-- to leave room for solderings and whatnot
standoffHeight = 15.0; //-- used for PCB Supports, Push Button and showPCB
standoffDiameter = 7;
standoffPinDiameter = 2.4;
standoffHoleSlack = 0.4;
```
