Speed Stacking / 疊杯

thingiverse

A decade-old notion has finally taken shape in my mind, and today I've brought it to life. This project is a competitive stack of cups that started as a mini cup concept, but after creating 3D models, I realized the wall thickness was too thin for such a design. To overcome this, I continuously scaled up the model until it was slightly smaller than a standard competition cup. The reason it didn't get any smaller is because stacked cups need to be stackable and foldable. Increasing only the interior or exterior thickness seems feasible at first but leads to interference problems when trying to print. To avoid these issues, the wall thickness needs to be extremely thin, which results in printing failure. My design was based on a standard 0.4 nozzle, and I recommend a minimum wall thickness of 0.8mm for optimal results. However, I believe the ideal thickness would be 1.2mm, similar to three-layer nozzle sizes, resulting in a more beautiful print. Due to printing time constraints, I compromised by making the cup body 0.8X thick. This project is a fun DIY endeavor, perfect for creating your own stacked cups. If you plan to use them competitively, it's best to purchase official certified cups. After printing, the cup body may feel soft and fragile. To achieve better print quality or strength, consider replacing the nozzle with 0.2 or 0.1 sizes and adjusting parameter settings accordingly. This might improve appearance but won't necessarily affect the structure's overall softness.
