espresso cup / egg up

thingiverse

Initially, I was inspired by Jonemo's office chair cup design but decided to modify it for personal use. Using Tinkercad, I removed all the legs from the original model, although some remnants of the leg marks still remain at the base. The modified cup is then placed on a custom-made base and printed with my Reprap Mendel 3D printer. However, I encountered an issue with its watertightness, which makes it unsuitable as a regular drinking cup. As a result, I use it to hold my SD cards on my desk instead of an egg cup for large eggs. For the printing specifications, it was printed at a 0.3 layer height and 40% fill; I am unsure if eliminating fill would resolve the watertightness issue. The dimensions of the modified cup are approximately 70mm tall with a top diameter of around 55mm.
