Useful 3D Printable Models (Part 3) - Slug Trap
In our series, we present easy-to-print 3D models that aren’t just visually appealing but also genuinely helpful in everyday life. This time, we’re heading to the garden with a clever solution against one of summer’s most common nuisances — slugs.
Store-bought slug repellents are often expensive, contain chemicals, and are not always effective. Thanks to 3D printing, however, there’s now a cheaper, eco-friendly, and reusable alternative: the Drunk Slug Trap — a beer-powered slug trap.
How does it work?
The concept is brilliantly simple. Slugs are attracted to the smell of beer, crawl into the trap, but thanks to its special shape, they can’t get back out—no chemicals, no pollution — just an innovative, 3D-printed design that solves the problem effectively.
Why do we love this model?
It’s completely environmentally friendly — no toxic materials or harmful additives needed. It’s reusable too: refill it with beer from time to time, and it’s ready to go again. Simple, efficient, and discreet — not a half-filled plastic cup, but a neat, well-designed little device that blends perfectly into the garden. It’s also easy to print, so even beginners can take on the project without worry.
What material should you use?
Since the trap will be used outdoors, it must withstand various weather conditions. Sunlight, rain, UV radiation, and temperature changes all challenge printed objects. That’s why PLA isn’t ideal — over time, it can deform or crack. A much better choice is ABS. It handles temperature changes well, resists moderate UV exposure, and doesn’t soften even in summer heat. It’s also durable, impact-resistant, and easy to clean, making it an excellent option for outdoor accessories like this slug trap.

Recommended filament: FilamentOn ABS. We recommend printing it in green, as it blends naturally with the garden environment — it can be discreetly hidden among plants or between decorative stones. Of course, you can also experiment with other colors if you prefer.
Summary
This model perfectly demonstrates how 3D printing can bring real value not only to the workshop but also to the garden. The beer slug trap is a more cost-effective, sustainable, and visually appealing alternative to store-bought options — plus, it’s reusable and environmentally friendly. If you want to protect your garden from slugs while reducing your ecological footprint, this project is the perfect place to start.
