Seven Ways to Install Magnets Into Your 3D Prints

Hackaday reports on a video breakdown of seven ways to embed magnets in three-D printed parts without using adhesive. The problem: simple friction fits loosen over time due to thermal creep, and super glue makes a mess. Slant 3D walks through alternatives like using cylindrical magnets with an arbor press to boost holding power, mounting magnets in side slots to avoid mid-print complications, and a clever trick where spherical magnets self-orient while locked in place. One surprise: using a ball bearing or washer on one side instead of two magnets extends the durability of your magnetic lock, since magnets are more brittle than stainless steel.
