ball jail - impossible box

thingiverse

While browsing Thingiverse, I stumbled upon a model that caught my attention right away. Upon slicing the downloaded STL file, however, I was left underwhelmed by the surface roughness. In response, I quickly created my own version and shared it as a remix. I printed this new design using Cura's tree support option without rotating it, and to my delight, it turned out perfectly.
