This holder was designed for a specific lab workflow: pre-mixing reagents or samples in 2 mL microcentrifuge tubes before distributing them by column into microtiter plate wells.
Each rack holds 12 tubes, matching a full microtiter plate column layout, allowing mixes to be prepared and dispensed sequentially without losing orientation.
Used currently in the Medical Microbiology Department at the Iuliu Hațieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania.
Key features
12-position layout aligned to microtiter plate columns

Compact, low-profile design for biosafety cabinets
Secure but non-binding fit for gloved, one-handed use and easy emptying
Printing recommendations
Material: PETG preferred
Default printer profiles should do the job.
Notes
Disinfection with 70% alcohol possible
Not intended for autoclaving unless you can print in autoclavable materials (e.g. PP-CF)
