+In a new file, include _sixinch_library.scad_. For each of the parts, there is module in the library where you can specify the most commonly used features like round and square holes, and pegs for supporting PCB's etc. The following examples are for Raspberry Pi 3 cabinet. <br>
+The deafult modules obviously does not support everything you need, but should give you a good start for further customization. Feel free to add functionality to the library.
