• Magnet placement tools are great because they remove finger fumbling while ensuring correct polarity every time. • [EmGi] has made a further improvement by makinga version that auto-feeds from an internal stack of magnets. • That is a trickier task than one might imagine, because magnets can have a pesky habit of being attracted in inconvenient ways, or flipping around and sticking where they should not. • [EmGi] solves this with a clever rack and pinion mechanism to turn a single plunger press into a motion that shears one magnet from a stack and keeps it constrained while the same magnet responsible for holding it to the tip takes care of dragging it down a feed path. • It’s easier to see it work in action, so check out the video (embedded below) in which [EmGi] explains exactly what is going on. • This design is actually an evolution of anearlier, non-reloading version.

- Auto‑Reloading Magnet Dispenser Can Feed Itself
EmGi has released an upgraded magnet placement tool that automatically feeds magnets from an internal stack, eliminating the need for manual handling. The design uses a rack‑and‑pinion system to convert a single plunger press into a shearing motion that separates one magnet from the stack and guides it to the tip. The same magnet that holds the tip also pulls the new magnet into place, ensuring correct polarity and preventing unwanted attraction. While the mechanism is more complex than earlier models, the design files are available on Printables and Makerworld for DIY builders. The system is limited to certain magnet sizes due to feeding dynamics, but a simpler non‑reloading variant works with any size.
