The 12 mm Test Tube Base is printed by 3DR-I to hold tubes securely with a snug fit, helping prevent tipping or sliding during routine bench work. Its four-leg structure gives exce llent stability while keeping the footprint small, which makes it ideal for crowded workstations, teaching labs, and quick sample handling. The fit of the 12 mm Test Tube Base is intentionally tight, so each tube stays in place even if the base is bumped. Your samples stay protected and easy to reach, even in busy, high-traffic environments where things move quickly. The Ø 12 mm openings are matched to standard 12 mm tubes, so tubes seat cleanly without wobbling. Available in 1-, 2-, 3-, 4-, and 6-tube versions, the base lets you choose the exact capacity your bench needs, from a single tube beside an instrument to a small batch at a prep station. The compact per-capacity sizing, from 50 × 50 × 60 mm up to 120 × 50 × 60 mm, keeps each version no larger than it needs to be. Made by 3DR-I with durable PLA and PETG materials, the 12 mm Test Tube Base is built to withstand daily lab use without losing function, and it is easy to wipe clean between uses. It is available in a range of finishes and colors, so you can match it to your bench or color-code it by sample type or workflow. A practical, economical way to optimize space and keep your samples in order, it is a dependable everyday choice for any lab that needs single tubes or small groups held upright, secure, and ready to use.
