I have a bunch of 1/8x1/16in Neodymium magnets lying around that I’m planing on using on a number of projects I have in the works. Here is the Amazon page for them, but a ton of places sell them.
I wanted to embed the magnets into Draftboard. To do that, I needed to find the right settings to get 1/16" depth in my engrave.
I pushed it in with a scrap piece of material, it is flush to the top, and now I can’t get it out again; I think that’s a success. Here are the settings that worked.
I made a simple circle in Inkscape that is exactly 0.125" Diameter. Here’s the file if you don’t want to recreate it.
