TestTubeRack Tag — Mini Lab Rack Keychain

A pocket-sized lab bench for the chemist, lab technician, or science teacher who spends their day around glassware. The miniature test tube rack silhouette — four rounded-top tubes rising at staggered heights from a solid base — is instantly recognisable on a keyring, a lab coat lanyard, or a bag zip. A quiet, well-made gift for a research colleague, a graduating chemistry student, or your own set of keys.

Design

Ready-made fixed design — no name or text engraving on this one. The strength of the piece is the clean cut-out silhouette, and the staggered tube heights read clearly even at arm's length. Supplied in white as shown.

Dimensions

• Length: 50 mm
• Height: 38 mm
• Thickness: 6 mm
• Integrated keyring loop, moulded as part of the body — no glued or riveted joint to fail
• Split ring included; keys shown in photographs are not included

Material and finish

3D printed in PLA at a 0.2 mm layer height, giving a smooth matte surface with a subtle horizontal grain. Solid-printed through the base bar and tube stems for rigidity, so the thin sections between tubes hold up to daily pocket and bag use.

Dispatch

Made to order in our own workshop. Dispatched within 5 working days of your order being placed.

Care

Wipe clean with a dry or slightly damp cloth. PLA softens at around 60 °C — keep it out of direct sunlight for long periods and never leave it on a car dashboard.
