AEG has a range of 58V tools such as mowers, chainsaws, whipper snippers and leaf blowers.  The batteries are large, mostly rectangular things with slides to hold them into the tool.  I needed a way to store these batteries and there was no shelf space - but I made this so I could attach this under the shelf.  Then I simply slide the batteries in and there they are, ready for use!

OK, you've got your handy-dandy magnet dispenser - https://thangs.com/designer/paul.wayper/3d-model/6mm%20x%202mm%20magnet%20dispenser-979605 .
But how do you actually put magnets into the baseplates and bin bases?

Well, grab yourself a 10mm x 1mm steel washer and an M2 10mm bolt (or just a thickish piece of wire) and get ready to make your very own magnet placer.

Put the two long pieces together at their obvious 'hinge' point, and thread the M2 bolt through the hole.  Glue the washer underneath the big cylinder, and then glue that down into the slot provided in the base.  Wait for the glue to dry and you're ready to go.

The push rod should slide easily through the hole in the cylinder, and the diagonal provides a 'spring' to return the handle to its position.  Don't do up the M2 bolt too tight, so the handle moves easily and returns to position.

When you're working, start by putting a SMALL amount of glue in every hole in the baseplates or bins.  Then start placing magnets.

The magnet should be attracted to the iron in the washer and should sit in the socket.  It should then be held in place as you put the placer in position over the hole.  The magnet should stick down from the placer socket a bit so it should be easy to locate the magnet in the baseplate or bin hole.  Squeeze the handles together and the pusher rod should go through the cylinder and push the magnet into the hole.  Your action should then go from pushing the top handle down to pulling the bottom handle up.  This allows the magnet to pull free of the washer, and the pusher rod to push the magnet into the hole and the glue.  The spring should then return the pusher rod into the cylinder, ready for the next magnet!

I'd recommend trying one or two out before doing an entire session.  That way you can get a feel for how much pressure you need to separate the magnet from the pusher and to push the magnet into the glue.

Gridfinity 6mm x 2mm magnet placer

This is a 6mm x 2mm magnet dispenser to make it easy to put magnets into a GridFinity baseplate or box.

I've found putting magnets into Gridfinity can be tricky.  You have to scrape one of these little disks off in your fingers, then push it into a hole.  Sometimes the glue squeezes out and now you have glue on your fingers.  Sometimes the magnet flips over as you put it in.  Now you need to handle this fiddly little magnet with gluey fingertips, and then scrape the next one off the stack...

Now you have an easy way to dispense these magnets one at a time!

Glue a magnet in the base piece.  Then put the slider in the side slot from the long end of the main piece, and put your stack of magnets into the top cylinder.  You'll know if you've got their polarity correct because they won't push all the way down otherwise.  Then when you push the slide up to the point where its hole is aligned with the cylinder, a new magnet pops in.  Simply push the slide forward again and now you have a magnet!  You can then pick this up easily with a scalpel blade, and put it into the hole on the GridFinity model.  Pull the scalpel back sideways and the magnet will stay in place.

Pull the slider back and at the right point another magnet will click into place.  Easy!

New features in version 1.2:

* Separated out the top and bottom, with pegs and holes.
* Removable magnet switcher with N/S so you can switch from the 'baseplate' orientation to the 'bin' orientation, in the one unit.
* The slider now has a cutaway on both sides of the magnet to make it easier to remove, while still making sure that new magnets only slide into the hole.
