What is a 3D-printed mounting bracket — and which clamp, clip, or dock do you actually need?
A modular mounting bracket 3D print is a bench-management part you download as an STL or 3MF file and print on the FDM printer you already own — no quoted-out custom bracket line item, no waiting on lead times, and no one-size-fits-all bench clamp 3D printed on a grid that doesn’t fit your rail. BenchWerkz ships the file plus a shared 20 mm backbone, so a bench clamp, a wall clip, a T-slot rail adapter, and a tray dock all mount on the same rail the rest of the catalog already uses.

Why a printed mounting bracket wins
The $80 supplier line item, refactored as a file
The bracket 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 four sibling parts (bench clamp, wall clip, rail adapter, tray dock) the supplier doesn’t sell together in this family.
Print one bench clamp 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 modular-mounting family
Three printable mounting-bracket parts to start
Three printable mounting-bracket parts to start — a grip-style bench clamp to a 45 mm benchtop edge, a two-screw wall clip, and a T-slot rail adapter. Each card links into the modular-mounting family at /families/modular-mounting. The family is growing, and a tray-dock sibling + additional bracket sizes land over the coming months.
