Kerf Compensation for Lasercutters

If you want to cut wooden boxes with a lasercutter, then the assembly will be easier if you generate the interlocking pieces with press fit. With the generator in the link below it's easy to get a reference cut with whom you can define the appropriate compensation.

1. Visit the [Kerf Compensation Site](https://maker.js.org/playground/?script=https://gist.githubusercontent.com/3kmch/0d7bbf16b193e010f20fee8230c8dd4c/raw/6421331633f911a834600829d68c2112e8c6d97e/kerf.js) and hit run.

3. Download the file and cut 2 pieces.
4. Look for the connection where the pieces fit together without play (or with press fit). https://youtu.be/Q_kA19hMXbM
5. Note the result of formula: (0.3 + 0.3)/2 = Kerf 0.3 | or (0.3 + 0.45)/2 = Kerf 0.375
6. Offset the outline of your shape on your computer accordingly (expand outer shapes and shrink inner).
