With the build of my first Multiboard I was tired of "Draw - Deinstall - Drill - Install - Screw - Draw - Deinstall - Drill - Install - Screw - Draw - Deinstall - Drill - Install - Screw - Draw - Deinstall - Drill ..."
And the holes 90% of the time were not really in the center ... So I created a drilling guide ... Always centered ... Way easier and faster to drill the needed holes.
The author marked this model as their own original creation.
