How to Get Started Building a MultiBuild Setup

Updated

MultiBuild is a free, modular 3D-printed organization system built around a 25 mm standard, and you start by downloading individual part files for free, then choosing which subsystem fits your space. It works best if you already have a 3D printer and want a storage setup for a workshop, garage, office, kitchen, or similar area that can grow over time. The system is organized into two main subsystems — MultiBoard and MultiBin — that are compatible with each other, so you can begin with one and add the other later.

Step 1: Download the parts you need

MultiBuild parts are available as individual downloads for free, and the project is described as the #1 most popular on Thangs, which is where the files are hosted. You do not need to download the entire ecosystem at once — pick the specific boards, beams, bins, drawers, or accessories that match your first project.

A practical first move is to download one board or one bin and print it before committing to a larger layout. This lets you confirm your printer's tolerances against the 25 mm standard before you scale up.

Step 2: Choose your subsystem

The two subsystems serve different purposes, and both connect to each other.

Subsystem What it is Best for
MultiBoard A modular connection board for mounting tools and holding heavy supplies; can be wall-mounted or stood on a desk Tools, heavy items, building 3D structures
MultiBin A modular bin and drawer system that can be connected, customized, mounted on boards, or turned into drawers Tools, craft supplies, hardware, household items

If your priority is hanging tools on a wall, start with MultiBoard and its hooks, shelves, and accessories. If your priority is sorting loose items, start with MultiBin. Because the subsystems are compatible, a common approach is to mount MultiBin units onto a MultiBoard so bins and tools share one surface.

Step 3: Assemble and expand

Everything is designed around the 25 mm global standard, which is what allows parts from different subsystems and accessories to connect. When you print, keep that spacing consistent so boards, beams, bins, and mounts line up.

The system is explicitly designed to grow with you: you can start with a single board or bin, then add hooks, shelves, drawers, and accessories as your needs change. This means you don't need to plan the final layout up front — print a starter piece, see how it fits your space, and expand from there.

Common starting points to consider

  • Wall-mounted tool wall: MultiBoard as the base, plus hooks and shelves.
  • Small-parts sorting: MultiBin bins connected together, optionally mounted on a board.
  • Drawer conversion: MultiBin units turned into drawers for a bench or cabinet.
  • Mixed setup: MultiBoard for tools with MultiBin units attached for hardware and supplies.

What to verify before you print a lot

  • Confirm your printer holds the 25 mm standard accurately, since every connection depends on it.
  • Check that the specific accessory you want is compatible with the subsystem you chose — the ecosystem is cross-compatible, but accessories are grouped by subsystem.
  • Start small: one board or bin first, then scale once the fit is right.

MultiBuild is used by 50,000+ makers across garages, workshops, offices, and kitchens, so there are real builds to reference if you want to see how others combined the subsystems before committing to your own layout.
