A Much Better Hatchbox Alpha LED Fan Shroud

thingiverse

Here is a new design for the cooling of a Hatchbox Alpha. My earlier designs tried using the stock fan and fan mount but I could never find a combination that cooled as much as I wanted to, hence this design. Now I can print pretty much anything! With the dual 'squirrel cage' fans I bought here (https://www.amazon.com/dp/B078SQS6MX) for ten bucks, the airflow to the nozzle is staggering in comparison. As you can see in the pics, the vent is very nearly 180 degrees and is one full centimeter wide all the way around. There is also ample room between the nozzle body and the fan shroud to prevent its melting due to nozzle heat. Designing a fan shroud for a delta type of printer is very difficult due to the fields of motion that the poles on the raft corners (I don't know what they are called) require. But the one area that there is plenty of room is above the raft, even with all axes in the 'home' position. So that is where I expanded into. In short, this design allows a full freedom of motion and cools like you won't believe. I have included four design types: one with two fans as an option and one with one fan as an option - and then one of each with the LED notches in case you have added that from my other design. Enjoy! PS- You may need to buy longer machine screws, I had to :/
