AAA battery case
thingiverse
Case to hold 4 aaa batteries. Fuzzy skin (outer only) option is recommended to rotate the cap easily. Thread of bottom part should be printed without fuzzy skin. I have attached the screenshot of Cura slicer to avoid fuzzy skin around thread area. In case of Prusa, it is also possible though the process is a little bit complicated. If you have stringing issue, split the stl in your slicer and print separately.
