SERVICE / 01
Replacement parts
Handles, couplings, brackets or supports that are broken and no longer sold — recreated from the original part or a photograph.

Technical sketch
Final model
We design the part that nobody sells.
From a photo, a sketch or hand-taken measurements — to a 3D file ready to print. Custom technical modeling for parts you can't buy anywhere.

DRAG TO COMPARE
[ 01 ] The method
From the conversation to a file ready to print
A measured process, thought out for people who have never drawn a part in 3D. Four steps, zero surprises.
01
Briefing
We measure the problem
Photos, approximate measurements, a hand sketch or just the idea. We ask the right questions to understand the part and its use.
02
Modeling
We design in CAD
Tolerances, fits and print orientation thought through from the start. It's not just pretty — it's printable.
03
Review
We prove & adjust
We send renders and, if needed, a printed proof. We fine-tune dimensions and details down to the right millimeter.
04
Delivery
We deliver the file
Model in STL/STEP, ready for any printer. If you prefer, we also take care of the final printing.
[ 02 ] Services
Modeling designed for the specific part
We don't sell a catalog. We design the part your situation demands — from a broken object to a brand new project.
SERVICE / 02
Functional prototypes
Test form, fit or mechanics before moving to series production.
SERVICE / 03
Brackets & adapters
Custom fixings for equipment, tools or electronics — jigs that don't exist off the shelf.
SERVICE / 04
IoT enclosures
Custom cases for Arduino, ESP32 and sensors, with exact openings for connectors, screens and antennas.
SERVICE / 05
Miniatures & replicas
Scale reproductions of objects, buildings or collectibles, made from photos or drawings.
SERVICE / 06
Custom merchandising
Objects with their own identity — logos, mascots or giveaways designed from scratch for your brand, ready for small runs.
SERVICE / 07
Laser engraving & signage
Safety and industrial signage for machinery — identification plates, control panels and warning labels engraved on wood, acrylic or metal.
SERVICE / 08
Domotics, IoT & industrial automation
Design, development and installation of residential domotics projects and IoT/industrial solutions — lighting, blinds, climate, monitoring and remote control — from idea to commissioning and post-installation support.

[ 06 ] FAQ
What people usually ask us
It depends on the complexity — from 1 day for simple shapes to 1–2 weeks for parts with mechanisms or tight tolerances. We confirm a concrete timeline after the briefing.
Both, your choice. You can keep just the file (STL or STEP) to print wherever you want, or ask us to take care of the printing too.
We make adjustments during the review phase at no extra cost, within the scope of the initial briefing. The goal is a part that actually works.
Yes. Many requests start with just a photo or a description. We help you get the right measurements during the briefing.
Yes. We're based in Maia (Porto) but take requests from all over Portugal, with shipping of the printed part or digital file delivery by email.
