Parametric drill stop

cults3d

I avoid drill stop designs where a screw touches the drill, as they tend to bind on the drill, especially on drills with thin blades, like wood drills. With this design, the entire inner surface of the drill stop holds the drill. To assemble it, you need an M3 washer, M3 nut and M3 screw, 12mm long (it may be a bit shorter for smaller drill diameters). The nut should fit very tightly to prevent turning. A tip for easy nut insertion: - Insert a long M3 screw through the screw hole - Place the nut on this screw and screw it until the nut is in position - Gently unscrew the long screw, leaving the nut in place - Install the washer and the final screw
