OpenSCAD Arduino Mounting library

The library has a variety of modules for creating Arduinos and Arduino mounts. Here is a basic description of the included modules. It includes all official boards through the Due. For examples see the included example SCAD.

##Dependencies

Using the library location instructions, checkout the pin_connectors library in the libraries folder, e.g on OSX this is done as follows:

$ cd ~/Documents/OpenSCAD/libraries
$ git clone https://github.com/tbuser/pin_connectors.git

This makes the pin_connectors/pins.scad dependency available.

If the libraries folder does not, exist, it will need to be created first. In the case of OSX:

$ cd ~/Documents/OpenSCAD/
$ mkdir -p libraries
$ cd libraries
$ git clone https://github.com/tbuser/pin_connectors.git

Follow the instructions for your platform.

Arduino Mounting Library Functions

arduino(boardType)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

This module creates an Arduino board with USB connector, power supply and headers.

bumper(boardType, mountingHoles)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

mountingHoles - (OPTIONAL) True or false for external mounting holes for bumper.

Create a simple bumper style encloser for a particular board

enclosure(boardType, wall, offset, heightExtension, cornerRadius, mountType)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

wall - Thickness of enclosure walls. Default is 3.

offset - Distance of PCB from walls.

heightExtension - Additional space at the top of the box.

cornerRadius - Corner radius for outside of box.

mountType - TAPHOLE, PIN - How the standoffs attach to the board either using tap holes for screws or pins.

Creates a box enclosure with a snap-on lid for a particular board

enclosureLid(boardType, wall, offset, cornerRadius, ventHoles)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

wall - Thickness of enclosure walls. Default is 3.

offset - Distance of PCB from walls.

cornerRadius - Corner radius for outside of box.

ventHoles - true, false for holes in the lid.

Creates a lid for the box enclosure

standoffs(boardType, height, topRadius, bottomRadius, holeRadius, mountType)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

height - height of standoffs

topRadius - Radius of top of standoff cylinder.

bottomRadius - Radius of bottom of standoff cylinder.

holeRadius - Radius of tap hole in the standoff.

mountType - TAPHOLE, PIN

This creates standoffs for mounting holes. These are simple cylinders that can be tapered. For custom standoffs use the holePlacement() module.

boardShape( boardType, offset, height )

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

offset - creates the shape offset from actual board size. Negative values create an inset shape.

height - default is pcb height but can be any value needed.

This creates the shape of the PCB with no holes. The default create a basic Uno PCB.

boundingBox(boardType, offset, height, cornerRadius, include)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

offset - creates the shape offset from actual board size. Negative values create an inset shape.

height - default is board height (including components) but can be any value needed.

cornerRadius -

include - BOARD, PCB, COMPONENTS What to include in bounding box, just the PCB, just the components or both (BOARD)

This creates a box whos dimensions are the extremes of the board.

holePlacement(boardType)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

This is used for placing holes and is the basis of the standoff module. holePlacement takes a child element and places it at each of the mounting hole centers for a given board.

components(boardType, component, extension, offset)

boardType - UNO, LEONARDO, DUEMILANOVE, DIECIMILA, DUE, MEGA, MEGA 2560, ETHERNET

component - ALL, HEADER_F, HEADER_M, USB, POWER, RJ45

extension - Extention off the board in direction of connector. The default is the standard dimension of the connector, but can be set to an arbitrary value.

offset - Offsets the connector cube in the other two dimensions.

Creates the components( headers, power and usb jacks) for a given board. Also used for creating punchout, by using the extension and offset values.

Problem with Uno bumper/mounting holes

Using this, it puts one of the mounting holes outside the base plate.
bumper(UNO, mountType=PIN, mountingHoles = true);

I fixed it with this updated bumper code (line 65 for me):

//Bumper mounting holes (exterior)
if( mountingHoles ) {
difference() {
hull() {
translate([-6, (dimensions[1] - 6) / 2, 0])
cylinder( r = 6, h = pcbHeight + 2, $fn = 32 );
translate([ -0.5, dimensions[1] / 2 - 9, 0])
cube([0.5, 12, bumperHeight]);
}
translate([-6, (dimensions[1] - 6) / 2, 0])
mountingHole(holeDepth = bumperHeight);
}
difference() {
hull() {
translate([dimensions[0] + 6, (dimensions[1] - 6) / 2,0])
cylinder( r = 6, h = pcbHeight + 2, $fn = 32 );
translate([ dimensions[0], dimensions[1] / 2 - 9, 0])
cube([0.5, 12, bumperHeight]);
}
translate([dimensions[0] + 6, (dimensions[1] - 6) / 2,0])
mountingHole(holeDepth = bumperHeight);
}
}

Y was referencing dimensions[0] instead of dimensions[1] for the first tab.

Thank you for the library! This will really come in handy.
