This D20 moves freely inside the frame of a larger D20. This makes it easy to roll without covering numbers up and adding additional random spins to a throw!
To up the torture test, we added an even smaller D20 inside a D20 frame inside a dodecahedron!
To remove the supports, we used dissolvable PVA material to act as scaffolding to hold the smaller D20 as it prints it the air!
PVA (polyvinyl alcohol) is a 3D printing material commonly used to create water-soluble support structures to achieve complex geometries. We have extensively tested preconfigured Ultimaker Cura profiles for optimal results when printing PVA support structures in combination with PLA material.
PVA is safe to print when using the recommended temperatures listed. To ensure a comfortable and healthy environment, we recommend 3D printing in a well-ventilated area.
