Hot End mod 3 Anet A6

For an improved and enhanced presentation, visit https://www.designuitinspiratie.nl/anet-a6-hot-end-mod/ This is Hot End 3 for the Anet A6. I have multiple Anets and they are used primarily for ABS and PET-G printing. However, these printers are not ideal for PLA printing due to a lack of cooling fans and heat breaks that restrict airflow around printed parts. The extruder remains mounted on the X-carriage, which doesn't require significant lightening since ABS printing is relatively slow. Recently, I have shifted my focus towards PLA printing as it offers cost savings. My motivation for creating this Hot End Mod was to enable PLA printing on the Anet and make the X-carriage as lightweight as possible. To achieve this, I designed a Bowden setup, added two "snail house fans" for cooling, and relocated the extruder above the controller. I omitted the cable holder and directly connected the cables to the Teflon tube. This configuration has proven effective. PET-G printing with cooling is another matter. Small or rounded objects print well with cooling, but larger objects are prone to warping. In such cases, I still prefer using my original ABS Hot End mod for better results. If you notice any omissions or have questions, feel free to ask. Parts List: 2x Teflon tube holder clips (3-4mm) Teflon tube (3-4mm) for 1.75mm filament Linear bearings from the Anet A6 printer (LM8UU) Extruder driver gear (came with the Anet printer) Nema 17 as Extruder motor (also came with the Anet printer) Spring for the extruder (also came with the Anet printer) 2x Snail house Fan 1X Hot end (heat break cooling fins diameter 22.5mm x 26mm but smaller will fit also) 1X Heater block heater and thermistor (came with the Anet printer) 1X Filament pressure wheel for extruder (came with the Anet printer) 1X 30x30mm Fan and holder for Hot End 1X M4 hex key head x 6mm 2X M4x 45mm and nuts 5X M4x 20mm and 3 nuts 8X M3x 20mm and 5 nuts 4X M3x 10mm and 3 nuts 1X 80mm M3 treated rod and 6 nuts (I used 2 M3x 40mm bolts instead) In the picture, I attempted to illustrate where each bolt and nut should be positioned. The Teflon tubing on the extruder and the spring are not depicted, as well as two M3x 20mm bolts that connect into the stepper motor – time constraints were a challenge!
