Magnetic X carriage

thingiverse

The design is to create a tool-free system for making adjustments on my 3D printer. I built this magnetic X carriage to quickly switch between different hotends, using a total of 10 magnets that hold the quick plate to the X-carriage. I'd love to hear your feedback so please comment if you have time! UPDATE: MGN12 carriage added! This design was inspired by Thingirobs Modular X car on Thingiverse. I give credit to him for the original design. ATTENTION: This part can be hard to print, especially the X-carriage. To improve adhesion, use hair spray! This design has very low tolerances, so you'll need to file: The underside of the holder The side notches of the holder The front notch of the holder The holes are very tight and might require drilling File until the parts fit together without a problem. I'm working on an instructional video, but ask questions if you have any problems. WHAT YOU NEED: All the old carriage parts 10x 5x3 Neodymium magnets 2x M4x20 screws M4 nuts (optional) Washers (optional) JST connectors (optional) XT30 connector (optional) FAQ: Q: Are the magnets strong enough to hold the hotend? A: Yes, there are 10 of them! Combined they create around 6kg (12lbs) of pulling force. Q: What about vibrations and movement? Will it create artifacts on the prints? A: No, as previously stated there are 10 magnets and 3 notches to keep the parts in place. The vibrations and movement won't affect the quality of your prints. Q: Will it hold a fan duct with fans? A: Yes! Q: Do I have to glue the magnets in? A: No! Q: You made the holes too small! A: No, your printer did! Use a drill bit and drill the holes by hand. Make sure not to remove too much plastic.
