Dig markers for metal detecting

I’m often detecting with my kid, and he usually marks the spots which he can’t dig himself. I also use markers for the “maybe” spots where the signal is questionable but I might want to check later.

Now the ground is frozen, so I decided to make a bit nicer markers for the spring which are easier to carry with you.

I made three different types of holders for the markers, depending on which gear I’m taking with;

• One for hanging from a carabiner

• One for attaching to a belt

• And one for attaching to a backpack or a pouch with a loop

Each of the markers has a neodymium magnet, and due to this they are not falling off from the holder even when carried vertically.

Also, due to how the magnets interact with each other, only one is released when you pull out the outmost one.

Printing:

You need 6mmx3mm magnets for the tips of the markers. The magnets are embedded, so you need to pause the print to insert them. 

Alternatively, just use the provided .gcode files and you don’t need to worry about getting it right. Just add the magnet when the print pauses. 

It is a very good idea to add a drop of superglue before inserting the magnet so it doesn’t get pulled up to the nozzle!

Note: The holders require two stacked magnets to be strong enough!

No supports needed!
