Improved part cooling for Snapmaker 2.0
Description
# IMPROVED PART COOLING FOR SNAPMAKER 2.0 While being a great all-rounded machine, I felt like the part cooling system of the Snapmaker 2.0 was a little lacking. So I designed this system that replaces the internal 25 mm fan with a 4010 blower fan, greatly increasing the airflow on the part, and reducing overheating and noise. There are 3 parts to be made, "Duct" and "Duct_outer" should be printed in PETG or any other heat resistant filament. "Outer_plate" can be either printed or milled. I've used the CNC head of my Snapmaker 2.0 and some 3 mm black acrylic that was included with the machine. # WARNING: SOME DISASSEMBLY REQUIRED. You'll be able to restore everything to the original configuration. I'm not responsible for any damage on your Snapmaker 2.0! For this project you'll need: - n.1 4010 24 V blower fan - n. 4 M2 x 8 screws # DISASSEMBLY - Remove the hot-end - Remove the left panel, removing 4 M2 x 5 screws. - From the back of the 3D printing head, unscrew the 2 rightmost M3 x 5. This will loosen the motherboard that you can see inside. - Gently move out the motherboard, being careful not to pull any cable. - Remove the fan connector. It's marked as "24V FAN1" on the back of the motherboard. - From the back of the 3D printing head, unscrew the 2 lowest M3 x 8. - Remove the cooling fan assembly, which is made of 2 plastic pieces and a fan. # NEW COOLING DUCT ASSEMBLY - Fix the "Duct" piece into the 3D printing head. The part has 2 small holes that align at the back of the 3D printing head. Use the same M3 x 8 that you removed from the original cooling system. - Assemble the other parts together. Refer to the picture for the correct order. Use M2 x 8 screws to keep the 4010 blower fan attached to the outer plate. The outer duck fits between the fan and the plate. and is kept in place with the same screws. - Connect the fan to the motherboard. Make sure that the cable is not too long: use the picture as reference. Some soldering may be required. - Fix the motherboard to the 3D printing head with the 2 M3 x 5 screws that were removed previously - Fix the outer plate to the 3D printing head with the same M2 x 5 screws that were removed preiously. Enjoy a better and more silent cooling system for your Snampmaker 2.0!
