Single Test Tube Holder

thingiverse

This tube holder was created to help with Covid-19 self-tests at schools. Many test come with one cardboard-holder for 20+ testkits, which forces teachers to improvise or risk confusing pupil's tubes when collecting them in one place. With these each pupil can have a single piece at their desk, to securely place the test equipment while performing the tests and avoid mix-ups or spills. The tube holder was created to hold most common tube sizes up to ~12mm diameter, the small hole can be used to place a swab with ~3mm diameter. It was designed to be printed without supports. I printed > 70 of these so far on my Anycubic Photon Mono.
