Description
Coin batteries are hard to distinguish from one another. This box keeps them alignd. Because it is fully parametric you can change it to your needs. FreeCAD is a free parametric CAD app. In the FreeCAD file you will find a spreadsheet in which you can change the number of rows, their names, size of the coins and more. Also the headroom for the coins is adjusted automatically so that they won’t fall out of their slots if you turn the box upside down.
The bottom and the lid are separate parts. Put a little piece of filament in the hinge to join them.
The print file (shown here) has room for four CR2450, six CR2025, five CR2032 and four LR44 batteries. In the printfile is a stop for a color change to emphasize the text.
