Super Easy Prusa XL Buddy Venting Cover with 24volt Noctua Fan

My personal issue with my XL printer started a few weeks ago. This is my first summer with my XL and I am finding out that my garage is just too hot for the XL to work. When the temp gets up to 90ish, the printer has one of the sensors that checks temperatures. It stops the printer to prevent issues. The MCU in the Buddy overheats. And to prevent fatal errors, it stops printing. The Buddy is encased in a metal housing without airflow AND the print heads are right above that area and while printing the Hot Ends blow the hot air down onto the Buddy area heating up the area beyond what the Buddy Board can handle. 

Update: able to print in my garage at close to 100 degrees!!

Goal with Remix:

1. Super easy to make
2. Simple Print without supports
3. Easy to get fan from Amazon 
4. Easy to connect to power (without step-down components) or any soldering.
5. Monitor your before and after Temperatures while printing to see if your new fan vent system works. (for me, during the summer my XL won't even print as my garage gets into the 90s and then it stops printing)

What you need:

1. Print in PETG with the back down like in photo
2. Buy Noctua fan, 24v A4x10 24volt from Amazon and use the wire connector to attach to the 24volt source on the Prusa
3. 4x3M 16mm screws to attach the fan to the cover
4. Allen Wench to attach fan and Torx 10 Wrench to loosen and tighten the cover screws
5. Long Phillips Screwdriver to loosen 24volt attachment screws
6. Ring Connectors with 5mm internal size to attach fan to 24volt power (see photos)
7. Pliers to crimp the wire to connectors to the wire supplied by Noctua

How to:

1. Print cover (Two options for 1-2 print heads or 5 print heads)
2. Shut off your XL printer and unplug just to mack sure.
3. Access the back of your printer
4. Attach fan to vent out with the 4x3M 16mm screws
5. Route wire in the cover as shown on the photos in the three wire holders
6. Find the Noctua extra parts and locate the connector that has two open wires.
7. Get two Ring connects and attach the wires to the Ring Connectors paying close attention to the negative and positive side.
8. Take off metal cover by loosening the 4 Torx 10 screws that hold the cover on. Over loosen but don't remove. The new plastic part is a little thicker than the metal.
9. Move out of the way the Print Head that is above the screws that hold the wires to the 24v supply, or if you feel comfortable, remove the board altogether to do next step.
10. Remove the screws on the 24volt connector.
11. Place the Noctua wire connector you just made with the screw to the 24volt connect along with the wires that were already connected.
12. If you removed the board. Make sure you put it back the way you found it. Push it in all the way.
13. Replace your Print Head you removed.
14. Now you are going to carefully place onto the printer the new cover with the fan. 
15. Connect the fan connector to the connector you attached to the 24volt power source.
16. Make sure your fan wire is not pinched or pushing on anything.
17. Watch out not to pinch the 3-5 Print head wires, make sure your route them through the right top cutout.
18. Line up the screws and cover
19. Tighten down the Torx 10 screws
20. Plug in your XL Printer and turn on your printer.
21. Make sure you fan works.
22. Print something fun!!!
23. Monitor your new cooler running printer

Kevin, thank you for making this print. I changed a few items with trying to get good airflow from the left to right and out. Made some wire guides. Also some vents on the top with a cover to prevent print junk from falling into the board.
