Hatchbox Alpha LED Fan Shroud

thingiverse

This is my final fan shroud upgrade to replace the stock one that came with the Hatchbox Alpha. I designed it with a smaller, more focused airway that concentrates airflow closer to the print head for better cooling results. Additionally, I wanted to illuminate the print area so I wouldn't have to use a flashlight every time I printed, which is why I added spaces for two LEDs on either side of the vent. Installing this fan shroud is relatively easy and you can reuse all of the screws and the mounting bracket that came with your Alpha. You will need to bend the stock metal support flat as shown in the pictures, though. There's very little room to work with but I aimed to create something that would fit the bill for condensed air flow, a small footprint, and bright lighting. To make this fan shroud functional, you'll need to purchase some additional parts. Sorry about that! Here are the extra components you'll require: 1. Two 5mm LEDs (I chose ultra-bright white ones) 2. A 100 Ohm Resistor 3. Wire with a female 2-pin adapter to connect to the main board I've included a schematic and a picture of where to plug the wires into a blank part of the main board. You'll need to remove the top cover of your Hatchbox Alpha to access the main board. I plugged mine into the Aux2 port at the 5v and ground connections, as you can see in the picture. I added the resistor to the positive leg and wired them in parallel, so they should last a pretty long time. The LEDs will be on whenever the printer is turned on, but if you want to add a small switch somewhere, you can do that too. Happy printing!
