Anet A8 Creality Hotend Mount

thingiverse

Please note that after assembling this mount I realized that I did not leave an opening for the nozzle fan, so the actual part has the opening while the part shown in the pictures does not. I modified the original file so that I could use the nozzle cooling fan from my Anet A8. I also made some modifications to add recessed nut holders, a slight modification to the hot end cage to make insertion/removal of the hot end easier as well as adding a mount for a BL Touch style bed level sensor. Parts (2) M3 x 25 screws (14) M3 x 24 screws (3) M3 x 22 screws (1) M3 x 20 screw (8) M3 x 14 screws (20) M3 nuts 66mm PTFE tube (1) Creality Ender 3 style hot end BL Touch (optional) (1) BL Touch style bed sensor (2) M3 x 18 screws (2) M3 nuts (2) springs Before attaching the hot end to the hot end cage I recommend that you disassemble the hot end and reassemble it yourself, taking care to 1) put some heat sink compound on the section of the heat break that is inserted into the (RED) heat sink and 2) ensuring that the nozzle/heater block/heat break is assembled correctly (mine was not assembled correctly from the factory). I also chose not to use the two screws that go through the heater block and then screw into the heat sink. I realize they are there for “structural integrity” but I think the assembly is rigid enough without them and they also provide a path to transfer heat off of the heater block and into the heat sink, which I would prefer to avoid. After reassembly, attach the hot end heat sink (RED) to hot end cage using (2) M3 x 20mm screws and nuts. When placing the heat sink be sure that the heat break set screw is facing outward. This will make future disassembly of the heat break easier. Embed (4) nuts in the back of the main plate at the (look at the back of the main plate) bottom right. Attach the main plate to the X carriage using (12) M3 x 24 screws and nuts. Start by threading all (12) screws through the holes and then place and tighten the nuts. Attach the belt tensioner to the X main plate using (3) M3 x 22 screws and (2) nuts. Attached the nozzle fan to the main plate using (2) M3 x 24 screws and nuts. Position the fan so that the opening faces straight down and is against the main plate. Place the extruder stepper motor on the main plate with the connector facing up. Attach the idler arm to the stepper using (1) M3 x 20 screw. Attach the tension arm to the stepper using (2) M3 x 25 screws. Insert a 66mm piece of PTFE tubing into the hot end. Attach hot end cage to main plate using (4) M3 x 14 screws and nuts, threading the PTFE tubing through the hole in the tension arm. Mount the hot end fan using (2 to 4) M3 x 14 screws. If you are using a BL Touch, place two M3 nuts in the mounting ledge on the hot end cage. Mount the BL Touch using (2) M3 x 18 screws that have springs inserted over the screws (see picture). Adjust the screws so that the tip of the BL Touch is 2mm-3mm higher than the tip of the nozzle. The BL Touch Offset is X=0.0, Y=-25.0 (Z will vary, but mine was -1.40).
