Drill bit holder tap holder

Instead of dialing in 3D printed hole sizes, drill/tap your holes to the final size. The holder can hold drill bits from 1/16" to 1/2". You might have to crank down the bolt with an allen wrench until you hear the layers separating. You can drill through soft material like plastic, but it is designed to enbiggen 3D printed holes to the intended size. Took a little less than 2 hrs with a 0.8mm nozzle and 0.4mm layer height. Only worth printing if you have: M4 nut M4 bolt at least 30 mm long Short screw for the slider piece Drill bit set/ tap set
