Work Sharp Precision Magnetic Stone Holder
I rotated it so it's standing up for the print so there wasn't and issue with the hole the guide rod goes through.
The Magnets that I used are from the following links:
1X https://www.kjmagnetics.com/proddetail.asp?prod=B882
2X https://www.kjmagnetics.com/proddetail.asp?prod=BX082-N52
The magnets i just pressure fitted in, and they fit great, but you may want to add a dab of glue.
