A 3D printer can be a practical addition to a home improvement toolkit, helping make everything from small replacement parts to custom organizers. It can save trips to the hardware store and offer inexpensive solutions for occasional needs, though printed parts should be used only when they’re suitable for the job.
Print screws and other small fasteners
A printer can produce screws and similar small pieces that are easy to misplace or inconvenient to buy individually. Before using printed fasteners in a larger project, check that the design and material are strong enough for the load and conditions they’ll face.
Make tools for occasional jobs
Online designs are available for items such as wire strippers, table vises, sanding blocks, and utility knives. Some pieces—like blades, springs, or metal screws—may still need to be purchased separately. Printed tools may not match the durability of a quality store-bought tool, but they can be useful for tasks you’ll only do a few times.
Replace or customize household parts
A 3D printer can recreate components that are damaged, missing, or in need of an update. Door handles and knobs are possible projects, as are furniture feet. Custom parts can add a personal touch, but they must be sturdy enough for their intended use—for example, a printed furniture foot needs to support the weight of the item.
Organize tools and supplies
Printed clips can bundle cords, while custom organizers can keep tools within easy reach. You can also make replacement handles for drawers or tool chests and covers that help protect items from dust.
Safety should guide every project. Parts exposed to significant heat, pressure, or other demanding conditions should be made from materials known to withstand them. If you’re unsure whether a printed component is safe or reliable, choose a part from a trusted manufacturer instead.
