First off, let me please ask that if you like these designs and find them useful please do like, follow and share my content. And if you have any ideas or concepts to modify the content I would love to hear!
UPDATE (28/10/2017): I have added this part https://www.thingiverse.com/thing:2611279 to my Thingiverse Page for those who wish to convert their roller carriage style Kossel printer to magnetic joints.
This is a magnetic ball joint upgrade for the Kossel Mini 3D printer range that use HIWIN style linear rails. The end effector is designed to use the e3d V6 style hotends as well as the various different clones that are available. This is a direct replacement to the rose/ball joint Micromake Kossel Mini sold by flsun.
The effector also allows for auto bed levelling using a limit switch and the nozzle as the means of detecting the bed surface location.
The kit can be assembled using a wide variety of parts, though has been designed around the use of 10mm magnetic ball joints.
The finishing parts for this upgrade can be purchased here http://www.chimesindustries.com/shop or the parts can be purchased from a variety of different online stores.
Print it, assemble it, try it out and let me know what you think! :) The increase in rigidity in using magnetic joints as well as linear guide rails on the Kossel printer designs really improves the print output and removes the 'slop' in the system.
I have added some images showing a possible part cooling setup for the magnetic joint setup. They can be seen here: https://www.thingiverse.com/thing:2364103 and here: https://www.thingiverse.com/thing:2364083 There are mounts for e3d V5 and V6 hotends (~23mm and ~25mm OD heatsink) and clone variants.
Also, if you do not have the ability to measure the length of the rods accurately to within tenths of a millimetre (0.1mm) then you may find this print helpful: https://www.thingiverse.com/thing:2355506 The pieces can be mounted to a piece of open beam aluminium extrusion ( e.g. one of your delta printer towers) and then each rod placed in the jig, adjusted to length and then fastened. This will ensure your rods are the same length and you do not experience any disconnects during printing and operation.
