1x2 Gridfinity Magnet Server

This 1x2 Gridfinity module holds a stack of 40 6x2mm magnets inside.  Roll the thumbwheel and one magnet at a time is delivered to the top tray, always in the same polarity.  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.  Only the center compartment can contain magnets.

To assemble, print all three parts (bin, lid and wheel).  Insert a magnet from the outside into the single magnet detent on the outside.  That magnet determines the polarity of the pile you insert because the server will only operate when the stack is attracted to the exterior magnet.  

Then insert the disc so the pin fits into the slot.  Finally insert a stack of up to 40 magnets. They must be attracted to the exterior magnet.  Reverse them if they are repelled.   Finally put the lid on.  It clicks into place and won't fall out.  Use the indents on the sides of the lids to pull it off.

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.

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

UPDATE 2:

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