OMT² - Hex Precision Tests for Bit Holders

thingiverse

Creating tools that are meant to fit standard bit holders demands an extremely high level of precision. To help you determine how precise your printer (or settings) is, or which type of OMT² bit you prefer so much, here are a few tests for you to try out. This test is simply a print test. To learn more about the project, visit: http://www.thingiverse.com/thing:1381028 Tight (No Tolerance) This test is exactly 1/4 inch in size, or 6.35 millimeters. Depending on your printer's precision, it will likely be too tight to fit any bit holder. Basic (Tolerance = 0.1mm) This test is slightly smaller than 1/4 inch in size, measuring exactly 6.25 millimeters. It should be the right size for use with OMT² handles, as well as standard bit holders. Loose (Tolerance = 0.2mm) This test is smaller than 1/4 inch in size, measuring exactly 6.15 millimeters. In case the basic version is still too tight, this one is the way to go. Print and try; there are no secrets here ^^. Let it cool down for a couple of minutes before trying it out, as the plastic will still be soft. Tips and Tricks: It's easier to fix a bit that's too loose than one that's too tight. For this, just put a tiny amount of Blu-Tack down the socket (the female part) and you should be good for hundreds of uses before needing to change it. Print Settings: Rafts: No Supports: No Resolution: 0.200 millimeters Infill: 100% Notes: This test is normally printed in less than five minutes.
