This design was asked for by Joergen Viljoen-Steel. I thought this was a great idea and I could have benefitted from this design myself during the build.
Instead of trying to cut the shape into the wood, a simple hole can now be cut out and the 3d part inserted. I have also included the STL for the Light too. Attaching the light to the unit requires an M4x6mm Screw.
