UltiMaker Y-coupler extender

This part was created as an internal benchmark tool by UltiMaker and is being shared so that users of UltiMaker materials can test their prints against the example prints we highlight during material launches. This part was designed by [Jeremy Evers](https://www.linkedin.com/in/jeremy-evers-18a79bb1/), a Technical Sales Engineer working at UltiMaker. The sample print shown in the images was printed using [UltiMaker PET CF.](https://ultimaker.com/materials/s-series-pet-carbon-fiber/)

This part can be used to test the dimensional accuracy of the UltiMaker Y-coupler [which you can find here!](https://www.thingiverse.com/thing:6184679)

If the Y-coupler slides easily into the extender and if the threads can be tightened properly, then the dimensional accuracy of both prints can be validated. The knurled texture on the extender is also useful for helping you dial in the visual quality of your prints.
