3D printed hooks can be remarkably strong: a modified PLA hook carried just over 250 kg in a rig built by 3D Maker Noob, a YouTube channel that designed hooks for Polymaker’s strongest-hook contest.
The key is printing the hook flat and adding perimeters rather than infill, so the printed lines follow the internal forces, according to CNC Kitchen, a YouTube channel that tests 3D printing hardware. Reddit users add that PETG is safer than PLA for anything that hangs for months.
Here is how to print hooks that hold, and where to use them.

How to Print a Strong Hook
| Setting | Why |
|---|---|
| Print it lying flat | Printed lines follow the hook curve, so they carry the load |
| More perimeters | Walls carry the stress; extra infill adds little |
| PETG for constant loads | PLA creeps and droops over time |
| Avoid sharp inside corners | Fillets spread the stress |
Safety: 3D printed hardware is not rated like store-bought hardware. Never use it where a failure could injure someone or damage something valuable: overhead loads, TVs, cabinets, ladders or anything you climb on.
| Use | Filament | Why |
|---|---|---|
| Indoor, light load | PLA | Stiff and easy, but creeps under constant load |
| Constant load, bumps, flex | PETG | Tougher; resists creep and impact better |
| Hot garage, car, outdoors | ASA | Heat and UV resistant; needs an enclosed printer |
| Grip, soft contact | TPU | Rubber-like |

What YouTube Creators Found About 3D Printed Hooks
These are findings from popular YouTube videos, paraphrased from their transcripts and credited. They are the creators’ experiences and claims, not my test results.
- CNC Kitchen (CNC Kitchen: “The strongest hook wins a $1,000 3D printer!”) explained the rules of Polymaker’s strongest-hook contest: one piece of PolyMax PLA under 50 g. His advice was to print the hook flat and add perimeters rather than infill, because the printed lines then follow the internal forces. He added that sideways loading is much weaker.
- 3D Maker Noob (3D Maker Noob: “How Strong Can A 3D Printed PLA Hook Be?!?”) designed three hooks for the same contest, then tuned settings: more shells, slower speeds, 100% concentric infill and wider extrusion. His best modified PLA hook carried just over 250 kg in his rig.
- On Reddit, users note that a PLA headphone hook slowly drooped under constant load, so PETG is the safer choice for anything that hangs for months.
Designing the Strongest PLA Hook
Frequently Asked Questions
How strong is a 3D printed hook?
Contest hooks have held hundreds of pounds briefly. Everyday hooks should be used for much lighter loads.
PLA or PETG for hooks?
PETG for hooks that carry weight all the time; PLA droops over time.
How should I orient a hook?
Flat on the bed, so the lines follow the curve.
Infill or walls?
Walls. Add perimeters first.
