Fire Resistant 3D Print Enclosure

This is a quick rundown on the 3D print enclosure I built for my Prusa MK3. In short, the sides of the enclosure are made from hardie backer (cement board); each sheet costs $11 at Home Depot and I needed two and a half sheets. The frame is constructed using 2x2 lumber, which was about $2 per eight-foot section - I think I used five or six of those. The glass used is one-eighth inch regular glass priced at $20. For ventilation, I employed the vents found here: The fan/hose adapter I utilized can be sourced from this link: www.thingiverse.com/thing:2297772. You can find more information on my designs, including STL files, at these URLs: https://www.thingiverse.com/thing:2790847 and https://www.thingiverse.com/thing:2790836. The temperature controller I used costs $6 and can be found here: amazon.com/gp/product/B075NF2QJ4/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1. For sealing, I used a dense foam weather stripping. An LED strip that I had on hand serves as the light source. A 2-pole switch is employed for controlling the light (on/off) and a 3-pole switch for the fan (manual on/off/temp controller on) - these switches are quite affordable, costing between $0.50 to $1 each. Lastly, the smoke alarm used is a First Alert Zwave model priced at $30-40; it integrates seamlessly with my SmartThings devices and sends notifications via text in the event of smoke detection.
