2x4 building brick

Print Settings:

• 0.2mm layer height
• 3 walls
• 25% infill

This brick is perfectly compatible with Lego bricks. It's easy to print and you can use all sorts of colors.

For me, a 100% scale worked perfectly with both the 3D printed parts and the original parts, but sometimes it felt a little loose.

If the parts are too loose, you can reduce the size to 99%, but feel free to experiment with that yourselves. :)
