Parametric Interlocking Tiles
by modilion, published
This interlocking tile script is a redo of makeme's 3D Interlocking Tiles to allow for easy oversizing of the notches, and improve difference padding.
If you are printing or lasercutting this part, 0.1mm oversizing is usually sufficient. If you are cutting with a CNC, you will likely want at least 0.5mm oversizing to account for the rounding on the inner corners.
