Mystic Turtle's Calibration Station

THIS TEST IS FOR CALIBRATING YOUR EXTRUSION MULTIPLIER AND OR OFFSETS TO ACHIEVE PRECISE DIMENSIONS ON A VARIETY OF PART FEATURES. NOTE: The default units in most of these files is millimeters. If you try to open these documents with inches as your default unit, it will end up being rather large. For your convenience, I have added a version of each of these files with inches set as the default document unit. NOTE: Please check out "PRO TIPS" and links to helpful YouTube videos that show you everything I am talking about on this page. Intro: I work at a fairly large factory in the research and development department. We have an aluminum extrusion press for making our own materials, and I check new die samples to ensure everything is within tolerance before we let it run through assembly. The short story is that I do lots of measuring and lots of fabrication/machining of prototypes in my line of work, and I am rather obsessed with precision. This test is for those of you who are also obsessed with precision and accuracy in your work. I tried to include most common measurements one would need to ensure accurate printing of a multitude of common parts/part features while making it easy to measure with a pair of dial calipers and a classic protractor. Instructions: To complete the full test, you will need a pair of dial calipers. As well as a 1/4"-20 bolt and a nut. (This is all in English Standard Units. Sorry to the rest of the world, if you need a metric version, please let me know, and I can make one.) There are two versions of each file. One is lower resolution, for much smaller g-code files. The drawback is that you will have facets on your filleted surfaces (for testing radius with a radius gauge). The other is high resolution, but the g-code file will be a doozy, and your printer may or may not like it depending on how fast it can process all those tiny fillets. NOTE: There is also a Mini Calibration Center version without text on it. When I printed it with a 0.6mm nozzle, the text was not legible, and the edges on that side were skewed. If you have a smaller nozzle, you may wish to test its small text capabilities. You can print these files at whatever settings you are trying to use regularly for your parts, though make sure you have your cooling and temps figured out to prevent warping of the base on the full test. If the full test base is warped, dimensions will be skewed! The mini calibration center file is a 1x1 inch (2.54x2.54 cm) square. It includes all the necessary features for a thorough calibration. Dimensions will be shown down to 0.0000" tolerance where necessary. (0.0625 is 1/16") Quote: "It is simple to design something that is quite complicated. Though it is quite complicated to design something that is simple." Conclusion: I sincerely hope this helps some of you on your journey to making accurate custom parts for your designs! This is the first "Thing" I have made for ThingiVerse. As I generally keep my designs to myself since many of them are business related, I tried to make it quite thorough and informative.
