round bricks compatible with comercial lego duplo system

thingiverse

These bricks fit perfectly into large Lego Duplo systems. I've successfully printed them from high-quality yellow PLA material and they work flawlessly. In addition, I've created new models featuring two distinct round designs, a standard 2x4 layout, and a compact 6x6 platform. All of these new designs have undergone rigorous testing with both PLA and ABS materials, using standard bricks as a reference point.
