OMT² - Hex Precision Tests for Bit Holders

thingiverse

Creating tools that are meant to fit standard bit holders requires a very high precision. To help you figuring out how precise is your printer (or your settings), or which flavour of that OMT² bit you like so much to take ...here are a few tests for you. This is just a print test. To know more about the project, visit : http://www.thingiverse.com/thing:1381028 Tight (No tolerance) This test is exactly 1/4" (or 6.35mm). Depending on your printer's precision, it will probably be too tight to fit any bit holder Basic (tolerance = 0.1mm) This test is slightly smaller than 1/4". It's exactly 6.25mm. It should be the right size to use with the OMT² handles, as well as standard bit holders. Loose (tolerance = 0.2mm) This test is smaller than 1/4". It's exactly 6.15mm. In case the basic version is still too tight, this one is the way to go. Notes : Print and try, there is no secrets here ^^ Let it cool down a couple of minutes before trying out, as the plastic will still be soft. Tips and tricks : It's easier to fix a bit too loose than too tight. For that, just put a tiny bit of Blu-Tack down the socket (the female part) and you should be good for hundreds of uses before having to change it. Print Settings Rafts: No Supports: No Resolution: 0.200mm Infill: 100% Notes: This test is normally printed in less than 5mn.
