What is a 3D-printed bottle holder — and which ring, cradle, or dock do you actually need?
A printable bottle holder is a bench-management part you download as an STL or 3MF and print on the FDM printer you already own — no $60 reagent-bottle line item, no waiting on lead times, and no quoted-out custom neck sizes. A BenchWerkz reagent bottle 3D print replaces the SKU and adds five shaped siblings on a shared neck-diameter index — a 50 mL wash-bottle cradle, a 100 mL reagent collar, a 250 mL media-bottle ring, a 500 mL buffer-jug dock, and a 1000 mL bulk holder — all sharing one snap-on label tab printable on the bench.

Why a printed bottle holder wins
The $60 supplier line item, refactored as a file
The line item on your lab budget is real. The cost-versus-time trade is not — a BenchWerkz file replaces the SKU, prints on the printer you already own, and adds five sibling parts (50 mL cradle, 100 mL collar, 250 mL ring, 500 mL jug dock, 1000 mL bulk holder) on a shared neck-diameter index the supplier doesn’t sell together in this family.
Print one bottle ring today. Print ten more next month, in the same PETG spool, on the same printer. The line item in your lab budget stays flat.
The bottle family
Three printable bottle-family parts to start
Three printable bottle parts to start — 50 mL wash-bottle cradle, 250 mL media-bottle ring, and the snap-on label tab that ships with every holder. Each card links into the bottle family at /families/bottle-reagent-holders. The bottle family is growing, and additional sizes land over the coming months.
