KeyChain Screwdriver Pocket Tool

thingiverse

This is a compact Pocket Tool that utilizes a common pen style screwdriver found at Autozone for $1.50 and also available at Microcenter, Home Depot and Lowes for about $2. This handy tool attaches to your keychain and includes: 1. A Phillips head screwdriver 2. A flat head screwdriver 3. A strong magnet for pulling screws out of tight spaces The magnet also securely holds the bit in place. You will need the following materials: 1. One 4mm x 10mm map magnet available on Amazon or at hobby shops. 2. A pen screwdriver tool with two-headed bits, measuring just under 5mm. The bits I used measured 4.95 to 4.96mm. 3. A small amount of glue - a tiny dab of Gorilla glue should be enough. Printing Instructions: 1. Print both STL parts: PocketScrewdriver07.STL and PocketScrewdriverCap08.STL Use a brim with 5 outlines to help keep the parts on the print bed. Set infill to 20% or more, shells to 3 or 4 for strength, and layers to 0.20mm. Assembly: 1. Apply a tiny dab of glue to the magnet and press it into the top of the inner part. 2. Once dry, the bits will easily slide into the screwdriver and make contact with the magnet. The magnet will hold the bit in place unless too much glue gets in the way. 3. Hold the cap at the bumpy end and firmly push the inner part into place. It should snap into place when seated properly. 4. Be careful not to hold your fingers over the springy "U Cuts" as they provide the spring action that holds the bit in place. 5. You can snap the screwdriver part into the cap either direction for a compact pocket mode or better grip on the tool.
