* Project description
[[file:make,%203.png]]

As regular user of this tool, I got annoyed that original cell
batteries run empty so fast and I have to worry about finding
replacements.

[[file:make,%202.png]]

So I added AAA battery compartment to the bottom, and now I can use
relatively large capacity and rechargeable NiMH batteries.

[[file:make,%201.png]]

The new problem I got is, how can I store and carry this thing
around. So special case is designed.

And special cover. Design utilizes [[https://www.amazon.de/gp/product/B00TACKU0O/][3mm x 2mm thick neodymium magnets]]
to keep cover magnetically attached to storage box.

My printer can print only 120x120x120 mm objects. So only the most
delicate part is protected. There is some empty space in the box
because of geometry of the tool. It can be used as small storage
compartments for something.
