I originally created this in Oct 2013 and made it available on Thingiverse.

Summary

This is designed to allow the mounting of an Azteeg X3 into the holes for an Arduino Mega on an Ord Bot plate. It has extra space under for running wire under the board because it takes up the space that is provided above and below. It also has mounts to assist in securing the wiring down.

Instructions

This was made in OpenSCAD. The OpenSCAD files are available for download. You can adjust all sorts of variables if you have different screws want more or less space below the board or whatever you like.

I have not successfully printed this yet, but I think that has more to do with my printer's capability than it does with the model. If you have some suggestions for improvements of the model's features, the OpenSCAD code or settings for best printing please leave a comment.

Here are the settings available and their defaults
// General
standoff_wall_thickness = 3; // How thick should the walls of the radius be?
height_base = 2; // How high should the base of that connects everything together be?

// Arduino Mega Specific
standoff_inner_radius_am = 1; // How big a hole should be in the middle of the standoff?
height_am = 3; // How tall should the Arduino Mega standoffs be?

// X3 Specific
standoff_inner_radius_x3 = 3; // How big a hole should be in the middle of the standoff? (X3 hole is about 3.8)
height_x3 = 15; // How tall should the X3 standoffs be?

// Settings for the cable tie mounts
height = 7;
width = 10;
depth = 5;
wall_width = 3;
