Hello and thanks for your interest. I only have PLA filaments but you can print with ABS too. Event with wooden filaments :-)

Hi! This looks tremendously fun. Is there a specific filament which you prefer for printing this? PLA is okay? What is best?

Hello Bastian and thank you for your kind words. All the blocks measure exactly 40 mm by 40 mm and the pins are only used to guide the upper blocks, not to fix like Lego pieces, for example. I do not know what to say about your problem, it may be your installation because I received no other complaints for this collection.

Hello, Wabby,

first of all many thanks for the realization of this great idea.
Yesterday I printed the first parts and unfortunately the single parts don't hold together at all. The pins and the holes have a tolerance of approx. 1.2 mm. The outer dimension of a cube is 39.9 x 40 mm. The accuracy of my printer should fit. Is it wanted that the stones are so "loosely" put together?
