W1209 Temperature Control Plus Step Down Module Housing

thingiverse

<h2>Summary</h2> Built this custom box to house my essential temperature switch and voltage regulator components. I designed it to work seamlessly with my 3D Printer, automatically turning on the enclosure fan when in use and shutting it off afterwards. For printing ABS, I shut down the unit to retain maximum heat. <h2>Required Parts:</h2> <ul> <li>DC Power Supply: This component needs a 12-volt output to power the W1209 12V DC Digital Temperature Controller.</li> <li>PC Fan</li> <li>W1209 12V DC Digital Temperature Controller (available at Amazon)</li> <li>M2.5x6 Screws</li> <li>M2.5x8 Screws</li> </ul> <h2>Possible Additional Parts:</h2> <ul> <li>Voltage Step Down: This component helps adjust the voltage level to a comfortable range for my 12-volt fan.</li> <li>Voltmeter: I added this to ensure peace of mind, knowing that the voltage is set within specifications.</li> </ul> <h2>Notes:</h2> I chose to use the voltage step down and voltmeter because I'm using a 19-volt power supply with a 12-volt fan. To prevent overvoltage damage, I adjusted the voltage step down until it reached a safe level. The voltmeter provides reassurance that I can walk away knowing the voltage is set correctly. The square posts on the box top allow for a snug fit without gluing. However, when setting up the unit as desired, applying a small amount of glue to the corners is recommended. Additionally, drill or cut holes for cables as needed. I routed the thermometer wire through the side vents and created a power in/fan out port on the side of the unit where it was required. You can easily add holes by drilling wherever you need them.
