3D Printing Ideas: 37 Useful Things to Print

The most useful 3D prints solve a small problem around the house: a hook in the right place, a drawer that finally stays tidy, a holder made for exactly your tools. Here are 37 ideas, sorted by room, with the filament to use and a tip for each.

A collection of small 3D printed objects: a hook, a plant pot, a phone stand and a box

Quick answer: start with small, practical prints such as cable clips, hooks, phone stands and drawer organizers. They print quickly in PLA, and you will use them every day.

Before you print

  • Measure twice. For anything that has to fit, measure the space and leave 1 to 2 mm of play.
  • Pick the right filament. Our PLA vs PETG guide explains which one suits which job.
  • Find models. Printables, MakerWorld and Thingiverse have thousands of free designs for every idea below.
  • Check the license. Many free models allow personal use only. Read our guide on 3D printing business ideas if you want to sell.

Tips for prints you will actually use

  1. Orient for strength. Layers are the weakest direction. Print hooks and brackets so the load runs along the layers.
  2. Add more walls. Three or four walls make small functional parts much stronger than extra infill.
  3. Use PETG for water and heat. Bathrooms, sinks, cars and sunny windows quickly soften PLA. See is PETG waterproof?
  4. Print a test piece. For tight fits, print a small section first instead of the whole part.
  5. Know the cost. Most small prints cost cents in filament. The filament cost calculator shows the exact amount.

Frequently asked questions

What is a good first thing to 3D print?

Something small and flat that prints in under an hour, such as a cable clip, a keychain or an SD card holder. You learn how your printer behaves without wasting much filament or time.

Where can I find 3D models to print?

Printables, MakerWorld and Thingiverse have large free libraries. Search for the idea, check the photos of other people's prints, and read the license before you sell anything you print.

Which filament should I use for useful prints?

PLA is fine for most things indoors. Use PETG for parts that get wet, warm or stressed, and ASA or PETG for anything outside. TPU is the choice for flexible, grippy parts.

Are 3D printed kitchen items safe?

Not for direct food contact unless you take extra steps. Layer lines can hold bacteria, and nozzles and colorants matter too. Stick to items that do not touch food, such as racks, holders and labels.
