+* 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.
+
+[[file:box.png]]
+
+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.
+
+[[file:cover.png]]
+
+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.
