These storage boxes make it easy for me to stack the paints in my suitcase, and I no longer have to worry about the paints being mixed up or spilling out due to being knocked over.

The "fortress"-style storage rack is redesigned based on SavageRodent's customizable shelving unit. I designed each set to hold six paints, which perfectly matches the length of my travel case. I deliberately split it into individual units so that I can easily create matching storage solutions for cases of other sizes by simply copying and pasting in TinkerCAD. Of course, you can also print several sets at once and then arrange and join them with plastic glue to create a storage rack of any desired length.

The "Vallejo"-style storage boxes are based on AdditiveTech's spiral gear cups, but the spiral structure has been removed, leaving only the cylindrical body. Each set consists of three storage boxes, which can maximize the utilization of space in my suitcase and allow for individual retrieval and flexible combination and assembly. However, since the surface of these storage boxes lacks a smooth adhesive surface, they cannot be fixed with plastic glue.
