These wooden blocks are specifically designed for use with Duplo bricks. As long as your printer settings are roughly the same as mine, their snap-fit effect is excellent. As early as a few years ago, I conceived these wooden blocks and intended to use them as cargo wagons for Lego Duplo trains. Of course, you can also use them for other types of building projects according to your own creativity, so you can freely choose the appropriate size. In order to find the most ideal tolerance fit, I spent a lot of time repeatedly debugging, and it is precisely because of this that I would greatly appreciate

Disclaimer: Lego Duplo bricks are not suitable for young children to play with, as there is a risk of them swallowing small parts. I have designed some particularly small models in these wooden blocks, so please carefully assess whether your child has the ability to play with such small items based on their age and developmental level.
