96-well 16mm tube rack

thingiverse

I'm reworking a tube holder for 16mm tubes. This one fits 96 tubes, which is a common size for nasal swab samples. I designed it to be printable on a Prusa printer with some adjustments. To print from corner to corner as shown in the photo, you'll need to rotate the model by 38 degrees around the Z-axis. Make sure the side with three flats faces down while printing to keep the object stable and prevent warping.
