Toys with real engineering inside them

  • Mechanical, electronics, firmware, and production under one team, not split across three vendors
  • PCB design and custom firmware behind buzzers, LEDs, sensors, and wireless sync, not an off-the-shelf module dropped in
  • Injection molded and laser cut enclosures sized to a real first production run, not a mass-market minimum
  • A documented process, from concept sketch through DFM review to a shipped, working product
  • Real STEM and EdTech kit experience: two shipped product generations of a classroom hologram kit for a USA client
  • A real office in Ludwigsburg, Germany, for a face-to-face point of contact on EU and adjacent-market projects

Our Toy & Game Product Development Process

The same disciplined process whether it is an electronic game accessory or a full STEM kit rollout.

01

Concept & Play Mechanic

The real interaction, the LED response, the buzzer cue, the scoring logic, is defined before a single part is drawn.

02

Mechanical & Electronics Design

Enclosure, PCB, and firmware are designed together, so the electronics fit the shape instead of the shape being forced around leftover space.

03

Working Prototype

A functional prototype is built and tested for the real interaction, not just how it looks on a render.

04

DFM & Tooling

Design is reviewed for manufacturability before tooling starts, so problems are caught on screen, not mid-batch.

05

Production Run

Your first production run is manufactured, inspected, and documented before it ships.

Where Our Toy & Game Engineering Applies

Different product, same engineering discipline underneath: mechanical, electronics, and firmware working together.

Electronic & Interactive Toys

LED, sound, and sensor driven toys that react in real time, not static plastic.

STEM & EdTech Kits

Hands-on kits that teach a real concept, built to survive a classroom, not just a shelf.

Game & Sporting Accessories

Scoring devices, wearables, and accessories built for real gameplay, not props.

Wearable Game Tech

Armour, costumes, and wearables with embedded electronics that hold up to real movement.

Injection Molded Toy Components

DFM-reviewed tooling for plastic toy parts and enclosures, sized to a real production run.

Firmware-Driven Devices

Custom firmware behind buzzers, LEDs, and sensors, written for your product, not borrowed from one.

What Toy and Game Founders Ask Us

Are you a soft toy or plush manufacturer?

No. We do not manufacture textile, plush, or soft-goods products. We engineer toys, game products, and kits that need real mechanical design, electronics, or firmware underneath them, injection molded and laser cut hard goods, not stuffed animals.

Do you build the electronics for an interactive toy, or just the plastic housing?

Both, under one team. We have designed the PCB, firmware, and enclosure together for real shipped products, an electronic LARP combat system with RGB LED health tracking, and a pickleball scoring device, so the electronics and the housing are engineered as one product, not handed off between two vendors.

Can you take a STEM kit from a first concept to a real classroom-ready product?

Yes, this is real, done work. The Lemur DIY Hologram STEM Kit shipped through two full product generations for a USA EdTech client, from a first working version to a lighter, more refined kit built to scale into classrooms.

Do you handle toy safety certification like ASTM F963 or EN71?

We design to the certification your target market requires, but CADLETE does not issue toy safety certification itself. That is a formal testing and compliance process handled by an accredited lab, not something an engineering partner signs off on.

We are based in Singapore, the Netherlands, or Australia, not the USA, does this work?

Yes. We already have real, verified clients across these markets, and a real office in Ludwigsburg, Germany, gives EU and nearby-market clients a face-to-face point of contact alongside our engineering team in India.

What is the minimum order quantity for a first production run?

There is no fixed minimum, we work at zero MOQ. Batch sizes are set to what your launch actually needs, not only large repeat orders.

If our toy needs an injection mold, who owns it?

You do, outright and immediately, not after hitting a volume target. There is no amortization clause and no lien on the tooling, the mold built for your product is yours from day one, for life, and we never resell it, repurpose it, or run it for another client.

How is our game or toy IP protected from being copied or reused?

A non disclosure agreement and any written IP paperwork your project needs are signed before any design file, schematic, or firmware is shared. All manufacturing is done in-house, nothing is subcontracted to China or a third-country vendor, so your files, molds, and IP never leave our facility or pass through any other party.

Working with Cadlete Designs has been a real pleasure. They helped with so many design aspects I hadn't considered and offered many suggestions that I would have never thought of. Professional, prompt, and always willing to go the extra mile. I was extremely lucky to have found them! (Patent Pending)

These guys are simply the best. They are professional and on time with the orders and take great care in understanding what it is you want done. They offer revisions on the product if it is off and they are so pleasant to work with, I would 10/10 recommend them to anybody looking for designs drawn up.

I have been getting a ton of design work done. Engineered specs, renderings for the past 3 years with them. The best thing about them is that they come back quickly and with great work quality. I really appreciate all the work they done for us and continue to do.
