Ender 3 Pro Hot end fun cover for ABS printing

thingiverse

Hello, i design and print this tool to avoid any air to go on my ABS 3D print. I took inspiration from a video on youtube "How To Print ABS On An Open Frame 3D Printer (Ender 3 / 3 Pro)", thank you NAUS. It actually will direct the flow of the hot end fun air no more on the part you are printing but on the back. Help in less warping, strenght of print and bed adhesion. Just print it as it is laying on the bed with support. To install it just unmount the metallic fun support, remove the screaw on the bottom left and loose the other 3 screws of the hot end fun and just push it inside. Insert again the screw you remove previously. I put two version, a SHORT and a LONG one. Didn't do any intensive test but the long one seems to be better. REMEBER to use an ABS version (printable without the tool itsself) and with the silicon noozle cover. Feel free to contact my for any information.
