Synapticulae Paint Station is a highly optimized 3D printable paint stick holder similar in dimension and use with the popular corrugated cardboard variant found in hobby stores across the world. I've optimized it so that it prints with zero supports or infills via Spiral Vase Mode. Simply load the 3MF file, print a few test pieces to figure out which best suit your vibe and print the final pieces.

The stick holders are CAD'd in FreeCAD and modified in Blender. Parts are tested on Bambu A1 Mini on PETG-HF, PETG (generic), and PLA Matte on 0.4mm stainless steel nozzle.
