Do it yourself 3D printed open back headphones based on the Aurorus Borealis headphones.
This project is based on the work of VasilyevichDrago. I canged the driver mount to accomodate the 50mm beryllium coated driver. The mounting system of the earcups was also changed to reduce spinning and make the slider friction easier changable.
To build iems you need a 3D-scan of your ear. Audiologists can make an impression of your ear for a small fee. To digitalize it, either find someone with a scanner, or try scanning it using photogrammetry.

After printing I sanded the parts to 800 grit and applied satin clear coat. This results in an apperance similar to annodized aluminium.
