Alphabet with enclosed magnets
The entire alphabet with holes for magnets. Magnets used are 6mm diameter and 3mm height. Perfect for young kids to spell out words on the fridge without worrying they swallow a magnet.
Add a pause after layer 18 (with layer height of 0.2) to insert the magnets and continue printing. You could add superglue as well to make the magnets sit super stable, without the glue you might hear a slight rattle when moving the letters as the magnets have a little bit of play in the internal socket.
