Hornady Primer Bottle Holder with 12mm magnets
thingiverse
I was looking for a primer bottle mount and found joshEE4thewin's awesome design, but was wanting to mount it with neodymium magnets to my bench so I wouldn't have to drill holes. For emptying the bottle I can just pull the whole thing off, reducing the possibility of wearing out or damaging the printed part from repeated removal and reinsertion of the bottle. This is setup for three 12 mm x 2mm magnets (nominally 11.9 x 1.7 mm for the ones i have from this set https://www.amazon.com/gp/product/B08F2DLJQC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). My bench doesn't do a great job of holding magnets, so I glued some additional, slightly more powerful, magnets to it for the primer bottle holder to stick to. I've included STEP files for both joshEE4thwin's original version and my remix in case you want to adjust the part.
