Tap Drill Handle

thingiverse

I created this tool out of necessity after years of manually tapping aluminum and steel parts. These "T" tools, with their wide design, are remarkably idiot-proof, allowing a lot of torque and precision. The design consists of three distinct components: the base, the lock, and a M3x20 screw. The lock simply slides into the base under a little pressure, then clicks securely into place. A M3 hole needs to be tapped first. I've printed several prototypes and tested them on PLA and ABS parts. Here are the print settings I used: Printer Brand: RepRap Printer Model: Prusa i3 Rafts: None Supports: None Resolution: 0.2mm Infill: 15% Post-Printing Procedure 1. Tap the M3 hole in the "BASE" part. 2. Slide the "LOCK" part into place under gentle pressure. 3. Screw the M3 screw through the "BASE" part. 4. Begin tapping immediately!
