Specimen Rack for Size Exclusion Chromatography

Hello Fellas! This is a specimen rack I designed for a friend of mine. It is used for Size Exclusion Chromatography. The lower part features a snap in mount for tubes with 16mm in diameter. For building this, you will need 3 M3x20 screws with matching threaded inserts. Also, you need 8 self-tapping- or wood screws with 3mm diameter and 8mm length. 10mm is fine too, although the screw tips might be visible. I included the step files for all the models, so you can adapt them to your use case. If you use Onshape you can directly clone the working directory and use the original files.
