Geocache Bolt Container with Magnet Hole

thingiverse

This is geocache bolt that has a hole for a magnet. The magnet I used was a Neodymium from Hobby Lobby. The magnet measure's 12mm x 2.5mm. These are very strong for their size. This is larger bolt, scale as needed. I printed in 0.16mm for a smoother surface because of the threads. 10/2023 Update: I have made the hole in the bolt both larger and deeper.
