This 1x1 gridfinity module holds a stack of 20 6x2 magnets inside. Roll the thumbwheel and one magnet at a time is delivered to the top tray. You can operate the magnet server with one hand.

There are interior compartments, but if you fill them with magnets they will prevent the magnets from sliding forward to be served.

To assemble, print all three parts (bin, lid and disc). Insert a magnet from the outside into the single magnet detent on the outside. Then insert the disc so the pin fits into the slot. Finally insert a stack of 20 magnets. They should be attracted to the exterior magnet. Reverse them if they are repelled. Finally put the lid on.

To use simply rotate the thumbwheel. Remove each magnet as it is served. If more than a couple of magnets are in the tray they too can prevent the stack of magnets from moving forward to be served.

I added a photo showing how to piggyback more magnets inside without interfering with operation. When the column gets short enough the magnets on top snap around and add to the column.

Prints without supports, but I print the lid with a 5mm brim.

UPDATE: Now there is a second lid you can print as an alternative to the original lid. The original lid is loose so you can remove it with one hand to see if the server is hungry for magnets. The new lid fits tightly so you will have to use two hands to remove it; however, it won't come off if you drop it.

UPDATE 2:

There is now a high-capacity magnet server. It isn't a gridfinity module, but it holds 100 magnets.

Update 3:

There is now a 1x2 Gridfinity Magnet Server that holds up to 40 magnets.
