My goal is to be able to make adjustments to my 3D printer without any tools being needed. That's why I designed this magnetic X carriage to be able to quickly change between different hotends. It has a total of 10 magnets which holds the quick plate to the X-carriage.
As always I'd love to get some feedback so please comment if you have time!
This part can be hard to print, especially the X-carriage. To help with adhesion use hair spray!
This design has very low tolerances, therefore you will 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 need a bit of drilling
File until the parts go into each other without a problem.
I'm working on an Instructional video! In the mean time, ask questions if you get any problems.
WHAT YOU NEED
All the parts from the old carriage
10x 5x3 Neodymium magnets (https://goo.gl/XW8Cm5)
M4 nuts (optional)
JST connectors (optional)
XT30 connector (optional)
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 the movement won't affect the quality of your prints.
Q. Will it hold a fan duct with fans?
A. Yes! It will!
Q. Do I have to glue the magnets in?
Q. You made the holes too small!
A. No, your printer did :D Use a drill bit and drill the holes by hand. Makes sure not to remove too much plastic
