INK CUPS vase mode

another vase mode project! I've been thinking about using printed ink cups for tattoos , as well as for other types of coloring like painting. One idea I had is to create fast ink cups that are eco-friendly by printing them with PLA. I believe these cups are pretty safe, or even safer than the ones from China. The normal ink cups often struggle to stay in place, but these interconnected cups hold very well. I printed them with a 0.6 layer width, 0.2 layer height, and a standard 0.4 nozzle, and they are watertight. Seven cups can easily hold enough shades for a good black and white tattoo with price 0,10€ to print in 20 minutes.
