OMT² Project - Hex Bits & Handles

thingiverse

Interchangeable Handles & Toolheads Compatible with Standard 1/4" Hex Bits & Handles Transform your trusty old screwdriver bit holder into a new tool by pairing it with one of the OMT² toolheads. Or, if you're desperate to tighten a loose screw but can't find your bit holder, print one up quickly. Even better, create a tool that doesn't exist yet! Using the guidelines below, your creation will be compatible with every OMT² toolhead/handle and every standard bit holder you come across. Here are all the parts made using the OMT/OMT2 tags: Toolheads Spanners Set Metric: http://www.thingiverse.com/thing:1420423 Spanners Set Inches: http://www.thingiverse.com/thing:1422494 Allen Keys Set Inches: http://www.thingiverse.com/thing:1381003 Allen Keys Set Metric: http://www.thingiverse.com/thing:1359260 Hex to Square 1/4" Adapter: http://www.thingiverse.com/thing:1379117 Bed Leveling Tool: http://www.thingiverse.com/thing:1359579 Blade Holder: http://www.thingiverse.com/thing:1359425 Blade Holder V2: http://www.thingiverse.com/thing:1417030 Nail Holder (Awl): http://www.thingiverse.com/thing:1359444 Rounded End Bit: http://www.thingiverse.com/thing:1363389 Whiteboard Precision Eraser: http://www.thingiverse.com/thing:1363296 Handles The Original OMT² Handles: http://www.thingiverse.com/thing:1359158 The Double-Sided Handles: http://www.thingiverse.com/thing:1363379 The Hex Male-Female Extensions: http://www.thingiverse.com/thing:1385071 Other Storage - Racks & Boxes: http://www.thingiverse.com/thing:1370801 Precision Tests for Bit Holders: http://www.thingiverse.com/thing:1381733 Guidelines For your tool bit to be compatible with 1/4" Hex bit holders and/or OMT² handles, it must follow these guidelines: It must be a six-sided polygon. All dimensions are given "flat to flat" (circumscribed diameter). Male (plugs for tool bits) height is always 5.5mm for tool bits. Tight: 1/4" (6.35mm) => radius: 3.175mm Basic: 6.25mm => radius: 3.125mm Loose: 6.15mm => radius: 3.075mm Female (sockets for handles) depth is always 6mm for sockets. One size only: 6.70mm => radius: 3.35mm TODO What needs to be done: Redo all the tools and bits in parametric (OpenSCAD). Create crazy, useless, or funny tool bits. Explanation This project is the evolution of the (now discontinued) "Open Multi Tool" project. The main difference between the two is the ability to use all OMT² toolheads and handles with any 1/4" (6.35mm) Hex bits and handles that you probably have lying around or can find in any hardware store around the world.
