Yes another Anet Hot End Mod. This Anet was only €150,- But we all know those printers need some improvements. In this case I wanted to make it for ABS, PET-G and PLA printing. The Extruder is not on the X car anymore, but at the controller. Connected with an PTFE tube to the new X car/Hot end setup. And Yes I made an all metal Y axis from scrap metal I had laying around. Now the printer is not so Breakable anymore :-)
Also made it possible to tighten the X and Y timing belt and the parts for the X axis are included. Not for the Y axis because it does not work on an original Anet. But if somebody still want to have those files I can still include them. If so, please let me know :-)
The Hot end E3D Heat Break dimensions diameter 22.5mm x 26mm is used(but the Chinese clones with an Heat Break diameter of 25mm also fits)
In this example I made the Heat Break myself and used the heater and heater block that came with the Anet Printer. So yes I didn't really use the E3D Hot End ;-)
I placed an peace of silicone backing mat between the Heater Block and the Heat Break as an heat insulator. This way the heater block transfers less heat to the heat break. Also the heater block is out of the air stream of the heat break cooling fan.
For cooling the printed part 2 Snail House Fans are used. One already came with the Anet printer itself. For these fans are 4 different lengths available. These are the four different lengths I needed for my printer. The different Hot Ends I use drove me to these 4 different lengths :-) Please see included Screen-Shot included with the photos. The ones I used for this setup are snail house fan duct 28.35mm L.stl & snail house fan duct 28.35mm R.stl shown in gray color on the Screen-Shot.
The 4 M4 allen key bolts are screwed in and so make their own threats.
The Extruder is just a standard direct drive design. The PTFE tube coupler is screwed in a to small hole. This way it taps it own threats. I left the hole to small so you can drill it out to the direct diameter and/or tap the treats you need. I know the lever looks very ugly :-) see photos. But it is a strong and working part and thus good for now ;-)
