I created this set of parts to work with my westune mag mixing plate from amazon. it will work with most mixing plates out there. it uses small magnets from ali express or amazon. i used the 3d printed 608 BB ball bearing while designing this thing so any 608 bearing will work.

I used CA glue to affix the bearings on the axles and the magnets into the pockets. I originally printed on an anycubic photon mono 2 printer but I had limited success also on my tronxy x5sa fdm with petg.

I double stacked the magnets to increase the coupling to the mixing plate. these work best with thin bottom containers that sit flat on the mixing plate.

P.S. make sure the polarity of the magnets is correct for the mixing plate. I put the magnets on the mixing plate so that they stuck on it then marked the top with a sharpie.
