Office Conditions Shell

thingiverse

I threw together a temperature and humidity project about a year ago to test the humidity of my home before and after installing a whole house humidifier. The result was terrible, with barely any net change even 90 days after installation. So this quickly became a decoration on my desk to monitor the conditions in my office. Having acquired a 3D printer and wanting to learn AutoDesk Fusion 360, I decided to give this project a little more life, plus help prevent damage when it accidentally falls off my desk because my cat likes to knock it around my office. Pretty basic shell/bumper that has vents next to the temp/humid sensor (in case I do make a lid), a rear hole for a powered USB cable, and support posts that line up with the PCB's drill holes. The support posts provide 1 mm clearance from the base of the shell, and the PCB fits snugly inside. If I had to build this circuit again, I would change the location of some components, as it current layout makes making a lid more time consuming. I've included a few screen grabs from Fusion, an STL file, and the Arduino Code (ino) file. The Arduino Code has a nice pin out table as well as some decent comments (I surprise myself sometimes).
