YAPP_Box

Yet Another Parametric Projectbox generator

Rev. 1.4 is the latest version.

This release breaks with previous releases in the extra parm "angle" in all the cutouts array's!!!

All plane array's now have this syntax:

//-- plane    -- origin is pcb[0,0,0]
// (0) = posx
// (1) = posy
// (2) = width
// (3) = length
// (4) = angle
// (5) = { yappRectangle | yappCircle }
// (6) = { yappCenter }

For your box to work with this release you have to add this extra parm (as "0") to all your cutOut-array-row's

THIS IS WORK IN PROGRESS!!

See: This Post (English) or This Post (in Dutch)

I have done my best but it can probably be done simpler. So, if you think you can help please contact me or make a Pull request.

TO DO

• I want rounded corners! Do you have an idear howto do that?? (done)
• modules (Hooks) that can be (re)defined by the user (almost there ;-)) (done)
• screw connector between the top- and bottomPlanes (for bigger boxes) (done)
• snap-ons in the ridges (done)
• Rotate rectangular cutOuts (orientation) v1.4
• anything else? Anyone?

How to program your Project Box

It all starts with some dimensions of the pcb you want your Project Box for and some other dimensions:

printBaseShell      = true;
printLidShell       = true;

// Edit these parameters for your own board dimensions
wallThickness       = 1.0;
basePlaneThickness  = 1.0;
lidPlaneThickness   = 1.0;

// Total height of box = basePlaneThickness + lidPlaneThickness 
//                     + baseWallHeight + lidWallHeight

baseWallHeight      = 7;
lidWallHeight       = 4;

pcbLength           = 88;
pcbWidth            = 49;
pcbThickness        = 1.5;
                            
// padding between pcb and inside wall
paddingFront        = 4;
paddingBack         = 1;
paddingRight        = 1;
paddingLeft         = 1;

// ridge where Base- and Lid- off the box can overlap
// Make sure this isn't less than lidWallHeight
ridgeHeight         = 3;
ridgeSlack          = 0.2;
roundRadius         = 2.0;  // don't make this to big..

//-- How much the PCB needs to be raised from the base
//-- to leave room for solderings and whatnot
standoffHeight      = 5.0;
pinDiameter         = 1.0;
pinHoleSlack        = 0.5;
standoffDiameter    = 4;

You probably want some cutouts in your box for connectors and stuff. For every plane (side) of the Project Box there is an array that holds the cutouts for that plane.

These examples are made with Rev. 1.3!

For Rev. 1.4 to work you need to add the extra parm angle in all cutouts array's!!

A picture is worth a thousand words ...

cutouts in the Right Plane:

cutouts in the Left Plane:

cutouts in the Back Plane:

cutouts in the Front Plane:

cutouts in the Base:

cutouts in the Lid:

Using the (new) angle parm (rotate around the x/y corner):

With yappCenter the rectangle will rotate around it's center point:

Base mounts:

pcbStands:

pcbStands fixate the PCB between the base and the lid.

Connectors between Base and Lid:

Inserts are great for making a screw connection between the base and the lid.

Thats it! Press F5 or F6 to see the results of your work!

Snap Joins:

Snap Joins Symmetrical:

(more) Base Mounts:

Hooks:

There are two type of "hooks"; at the inside of the box or at the outside of the box

baseHookOutside():

lidHookInside():
