I had so many batteries around I decided to make a holder to keep them all in one place. You can customize it for the size you like and as high as you need. I added comments with the sizes I use but you can make one for C or D size battery too, just measure the diuameter of the battery and add a few tenth of millimeters and insert the measure in the customizer's parameters. I was unsure of making the bottom open or close, but as alcaline batteries sometimes leak, I decided for a closed bottom so an eventual leak will be contained and will not ruin surfaces. ---------------------------------------------------------------------------------------------------- I created these eBay links where you can find components, filaments and spare parts at the best prices. These are just links to eBay and Aliexpress items, where I normally buy spare parts and materials for my printer and projects. Buying something throught these links will support a little bit these projects.
