Minimalist Dual Cooling Fan for Aquila / Ender 3 V2

thingiverse

This can clip right onto the hotend, no need to screw it on! if you choose to use a screw, an M3 x 8 will work fine. M2 x 16 or 20 can be used for the side fan cover. Rotate the shroud 90° on its face. For X axis Linear Rail - choose file that says Linear, otherwise choose Stock if you have wheels. Download the 4010FanDuct for a stock duct that usually comes with the 4010 Turbo fans, you may have to rotate it 90° so it is up right, bottom end faces down. If you would like the modified fan duct - try the file with Tall at the end, otherwise if your nozzle is shorter/higher up then go for the regular modified version. Its a difference of about 22 *Use the setting in your Slicer for the left side with the modified fan ducts. Because the fan ducts are small parts, its better to use a smaller layer height. I was able to use 0.12 and an initial layer height of 0.16 with a 0.4mm nozzle. Its better to make the Initial Bottom Layers up to the layer it starts printing walls on the inside, I think around a dozen. You can have 100% infill for the ducts because it is a small part anyway and takes about 30min to print even for PETG. *You may have to remove the pins from the fans electrical connector for the **Front Hotend Fan** inorder to fit throught the front hole. Its possible if you take something like a sharp point of a knife or pin or tiny flathead screwdriver and gently push the metal tab or slightly pry up on the plastic of the connector. *The 4010FanCover is for the side turbo cooling fans and is optional. Search for a 40mm fan cover for the front fan. This is a total redesign of the model (not my original design) in the video using dual 4010 turbo cooling fans with stock ducts. It is a minimalist design, u can use a 4020 or 4010 hotend cooling fan, or even your own ducts if it can fit (the modified Tall or short/regular is recommended). This is meant to fit on a Voxelab Aquila or Ender 3 V2. Either Stock X plate, or with using a Linear Rail. For the Stock machines, you may have to grind a bit of a corner of the plastic fan housing to clearance the bolt head of the bottom wheel. The original designer's youtube video goes into detail about it. I mainly changed this so stock ducts can be used rather than printing ones because the stock ducts are best for airflow apparently, as someone tested in another video. I based it from this model from here https://www.youtube.com/watch?v=TJxpiLG73dM **Video is not mine, but my model is based on it. I spent hours and days working on this with little CAD experience. I did my best and made many versions or iterations to get it perfect! I offer this for free, and if you do end up using it, please consider making a donation as it would be worth my time. thank you. https://www.paypal.me/andrewleduc https://www.paypal.com/paypalme/andrewleduc any thoughts or changes you think I should make, please comment! id really like any input
