These bases are an alternate I designed to use with ThatRobHuman's great workholding system inspired by Omnifixo. I tried the versions using the countersink magnets, but I didn't feel like the ball or the base was quite secure enough.
So, after a few iterations, I came up with this design - the ball joint is designed for a press-in fit that's further secured by a trio of the 6x3mm magnets that are used nearly everywhere else in the 3D printing world. And then, a 12x3 magnet in the base means it stays where you want it to on your magnet plate, even if it's a cheap $9 piece of spring steel from Amazon.
Printing: Don't use PLA since it will lose grip over time. I've used ASA and ABS. PETG would probably be OK too. Make sure your tolerances are dialed in.
Assembly:
- Put one of your clamps in the base - the 10mm ball should click in. If it doesn't, your print tolerances might be a little off.
- Insert the 3x 6x3mm magnets, all with the same pole aimed in at the ball. Press them all the way in and they should stay in place without adhesive.
- Check the polarity of the 12x3 magnet so that it's cooperating with the other magnets. Then add a drop of super glue and press into its pocket.
