OMT² Project - Hex Bits & Handles

thingiverse

Interchangeable Handles and Toolheadscompatible with the standard 1/4" (6.35mm) Hex Bits & Handles Take your good old screwdriver bit holder and use it with one of the OMT² toolheads and you have a new tool. Or you so desperatly need to tight that loose screw and you can't seem to found your bit holder, print one up ^^ Even better, you need a tool that doesn't exist, just make it using the guidelines listed below and your creation will be compatible with every OMT² tooolheads/handles AND every standard bit holders you can come upon... Here I'll be listing 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 needs to follow this guidelines : It must be a 6 sided polygon All dimensions are given "flat to flat" (Circumbscribed diameter) Male (Plugs for tool bits)heigth 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/funny tool bits Explanation This project is the evolution of the (now discontinued) "Open Multi Tool" project. The main difference between the 2, 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 and/or that you can found in any hardware shop around the world.
