The fastest way to fasten/unfasten a lace-up shoe.
You need 3 neodimium magnets of 12 mm in diameter and 5 mm in height for each piece (12 for the complete set). In the EU you can purchase at Supermagnete.
On each piece, insert the magnets with the same pole up and in the opposite with the same pole down. To facilitate the operation, mark the faces of the magnets with a marker.
Once the pieces are printed, insert the magnets into the holes and glue the lids with acetone or PVC cement (if it is ABS).
This design avoids to some extent the impact of the magnets and their possible deterioration over time.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
