3D model description

Designed to be easyly printed without support, safe for kids with beveled corners and scaled for 16mm standard marbles (you can scale up or scale down your prints, if you want).

These modular blocks are based on a square shape so each block perfectly feats with all the others, no matter the direction you put it.

So you can craft an infinite variety of circuits with these blocks and the extension packs : &

This is not an open-source project but feel free to create your own compatible blocks and share it to the community. As long as you're not reselling my own blocks, for sure :-)
I would only ask you to credit me "Wabby's Land" for the original design and put a link to the starter pack in your model descriptions.

Hello Frank, yes you can simply print all the block in the default orientation (bottom in the print bed, indeed). They all designed to be printed as simple as possible. I hope you enjoy it.

What is the best print orientation ? is it normal the bottom to the print bed ?

Hola compre los paquetes mi duda es, con que densidad de relleno es recomendable?

How many of each piece should be printed?

Merci, ce genre de retour fait plaisir. Amusez-vous bien avec vos enfants !

Excellent travail ! L'impression est en cours pour quelques jours encore mais les enfants vont être ravis !

hello I love this object !

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?
