For when you wanna know what time it is, and it's ALWAYS Hammer Time.

I got a bit crazy with the mini Mjolnir magnets a while back from https://www.thingiverse.com/thing:2485766 and decided to do something with them.  I set the holes on the back to house the same 3mm x 6mm magnets as the Mjolnir model, so the front is “clean” if you only want to put 12, 3, 6, and 9 on there or load it up fully.  No supports required when printing.
