This is a 7.1mm bit version of my 4.5mm: http://www.thingiverse.com/thing:2008778 Step 1. Acquire a 7mm bit that you need to have on hand always. Most makers will have several sets available - if not, check out your local hardware store, electronics shop, or even dollar store for a set. Budget $1 to $3. Step 2. Print it with 100% infill - insert the bit and Step 3. Attach it to your keychain or EDC multi tool ring. Print Settings Printer: Maker Select i3 and PowerSpec Ultra Rafts: No Supports: No Resolution: 0.20 Infill: 100% Notes: The fit should be snug with a tightness that favors the part holding the bit when used. Minimal filing may be necessary. Troubleshooting: If the part is too tight, scale the size in the slicer software up by one or two percent and try again. If the part is too loose, scale the size in the slicer software down by one or two percent and try again.
