Preparing the Enclosure for the ElectronicsI had to print three parts to get everything to fit snugly inside my new enclosure. First, I needed a mount for my Raspberry Pi. I found an appropriate one on Thingiverse: http://www.thingiverse.com/thing:37889 .
Next I needed an Arduino Uno/grbl mount: http://www.thingiverse.com/thing:33327. Finally, I needed a fan grille, but I could not find any out there that I could download and print directly. I then came across this wonderful parametric fan grille that one could download, configure and print, brilliantly written by John Ridley a couple of years ago.
I downloaded the scad file, opened it using OpenSCAD, "The Programmers Solid 3D CAD Modeller" (free). All I had to do was take some measurements with my caliper, enter all the parameters the program required and, voila! a perfect fan grille, perfectly sized, ready to be printed:
In a pleasant surprise, printing went off without a hitch. Here are the printed parts:
The next step was to mount the emergency-stop button, fan and fan grille to the top of the box:
I then used screws and trapped nuts to put the rest of the enclosure together.
With the enclosure and mounting parts complete, I am ready for the next step: Turn the Raspberry Pi into a dedicated gcode sender that can be wirelessly remote-controlled from any computer or tablet in the house.
