Anycubic I3 Mega Hotend housing by 3DMath - open Front Grill

thingiverse

I've opened the front grille and enlarged the recess at the bottom for the hot end so that you don't have to turn the hot end block. A few M3 screws and nuts are needed for the side reinforcement of the side parts on the case. Alternatively, larger screws can be used and directly drilled into the plastic if no nuts are available. For the installation of the part cooling, longer screws are required. The complete rebuild: Radial fan: 50x50x15 standard Sunon or similar. Hotend fan: Sunon HA40101V4-000U-999, 40 x 40 x 10, so that it remains quiet. Or take the one with 11.9 cfm for best cooling: SUNON EB40101S2-999, 40 x 40 x 10 mm. (A Noctua is still installed on my picture.) The part cooling installation is as follows: https://www.thingiverse.com/thing:3129964 This should give you the best hot end and part cooling. I've done all these rebuilds and stick to this method. You can print everything in PLA, but better with PETG or ABS. However, PLA holds up well for me and I never exceed 220 degrees Celsius. P.S.: You only need to remove the 4 side screws and you can then easily access the hot end without having to remove the entire housing.
