FreeCAD | Laser Cut Interlocking workbench

https://github.com/execuc/LCInterlocking

Step 2 (after the basics #37) is the Laser Cut Interlocking workbench.
There hasn't been any development on it in 10 months as of the time of writing.

**NOTE**
This module looks _super cool_ but there's a huge disclaimer around it being ***still experimental and not reliable***.
The release for FreeCAD 0.19 is also _still in progress_ so we should run 0.18 (which is currently the latest stable version anyway).

_Definitely_ trying this out.

This is a cool little video on it in use as a good example. Uses the laser cut interlocking workbench, adds tabs and then goes into the part design workbench to adjust them and create holes where needed with pockets too:
