34 As regular user of this tool, I got annoyed that original cell
35 batteries run empty so fast and I have to worry about finding
38 [[file:make,%202.png]]
40 So I added AAA battery compartment to the bottom, and now I can use
41 relatively large capacity and rechargeable NiMH batteries.
43 [[file:make,%201.png]]
45 The new problem I got is, how can I store and carry this thing
46 around. So special case is designed.
50 And special cover. Design utilizes [[https://www.amazon.de/gp/product/B00TACKU0O/][3mm x 2mm thick neodymium magnets]]
51 to keep cover magnetically attached to storage box.
55 My printer can print only 120x120x120 mm objects. So only the most
56 delicate part is protected. There is some empty space in the box
57 because of geometry of the tool. It can be used as small storage
58 compartments for something.
