What Is MultiBuild and What Does It Offer?

MultiBuild is a free, modular 3D-printed organization system for workshops and homes. It is built around a 25 mm standard and consists of two main subsystems — MultiBoard (connection boards for mounting) and MultiBin (bins and drawers) — plus hooks, shelves, and other accessories. Individual parts can be downloaded for free, and the system is designed to expand as your needs change. It suits makers who already have a 3D printer and want a customizable alternative to fixed shelving or store-bought bins.

The two core subsystems

MultiBuild is divided into multiple subsystems, each focused on a different aspect of organization and each compatible with the others.

MultiBoard

MultiBoard is a modular connection board. You can:

• Mount it on a wall or stand it on a desk
• Use it to hold tools, heavy supplies, or even build 3D structures
• Expand it with hooks, shelves, and other accessories

MultiBin

MultiBin is a modular bin and drawer system for tools, craft supplies, hardware, and household items. Unlike conventional bin storage, it is designed to be adaptable:

• Connect bins together
• Customize their function
• Mount them on boards
• Turn them into drawers

Because both subsystems share the same 25 mm standard, parts from one can be combined with parts from the other.

What you get

The site describes the system as "free" and states that you can "download individual parts for FREE." No pricing details, paid tiers, or account requirements are specified in the available information, so treat the free-download claim as applying to the parts themselves rather than assuming anything about hosting, accounts, or future paid offerings.

Who it is for

MultiBuild is aimed at DIYers and makers organizing a workshop, garage, office, kitchen, or similar space. The site reports real builds from 50,000+ DIYers and notes that it is the "#1 Most popular on Thangs," a 3D model repository.

It is a reasonable fit if you:

• Own a 3D printer and are comfortable printing functional parts
• Want an organization system you can grow and reconfigure over time
• Prefer a shared standard (25 mm) so parts stay compatible as you add more

It is likely not a fit if you do not have access to a 3D printer or prefer buying ready-made storage rather than printing and assembling it yourself.

How to get started

1. Go to multibuild.io and browse the MultiBoard and MultiBin sections.
2. Download the individual parts you need — the site states these are free.
3. Print the parts on your 3D printer.
4. Assemble and mount: attach MultiBoard to a wall or place it on a desk, then add hooks, shelves, bins, or drawers as needed.
5. Expand over time by printing additional compatible parts.

The expected result is a custom setup that adapts to your space rather than a fixed unit you have to work around.

Key things to know before you commit

• Shared standard: Everything is designed around the 25 mm global standard, which is what keeps the subsystems compatible.
• Modular by design: The system "grows with you" — you are not locked into a single configuration.
• Community-validated: The 50,000+ maker figure and the Thangs ranking suggest a large existing user base, which can help when looking for build examples or advice.
• Printing required: This is a 3D-printed system, so your results depend on your printer and materials. The available information does not specify recommended filaments, print settings, or load limits, so verify those against the individual part pages before printing heavy-duty mounts.
