PrintABlok are interlocking building toys created by the 3D Printing Professor, designed towork well on home 3D Printers. PrintABloks can be built in all 6 directions, allowing for gravity defying building unlike any other building block out there.

This is the base PrintABlok set from the PrintABlok Mech kickstarter. It includes many blocks that allow for creation of amazing builds with advanced geometry. PrintABloks also make excellent prototyping tools.
