Magnetic connector for fan - ROBO3D

thingiverse

I've been using these magnetic holders for two years now and they're performing flawlessly. They offer lightning-fast attachment to the carriage, effortless replacement with other fans (quieter or more powerful), and the main benefit is rapid access to the hotend. As you can see, I've designed a compact holder that fits snugly into the Robo R1 carriage and secures with a single screw. This holder features two 6x6 round neodymium magnets that are pressed into the holder's holes using unstripped wire. The wire is soldered to the right wires on the printer (the PWM fan output on the RAMPS board, located in the same spot as the factory fan). Fans measuring 40x40mm are placed within the fan holder and their wires connected in the same manner as the holder's, with magnets pushed into holes. Some glue can be used for added security, but it's not necessary if the printout is tight. The printed pins that fit the fan holes can be treated with a soldering iron tip to melt them, keeping the fan firmly in place. It's amusing that I initially wanted Robo 3D team to see these designs before sharing them publicly, but it seems they weren't interested. Now, I'm making this idea freely available to everyone. These models are suitable for the E3D v5 head - longer than the factory one. It's a good idea to check if it will fit your printer before printing. That's all folks! Enjoy printing and using these designs. https://youtu.be/fiJ-MZ5ckRg
