Vespoo — A Smarter Way to Make the Wooden Toy
Wooden toys are one of the most beloved categories in product design — tactile, durable, and timeless. Vespoo started by asking one question: what if you kept everything that makes them great, and redesigned the parts that make them hard to produce?
The result is a miniature scooter — a Vespa in spirit — built from two processes rather than one: 3D printed PLA for the complex curved body, and CNC routed birch for every round, flat, or simply-profiled component. The two materials find each other naturally in the final object: warm wood against bold colour, rough-matte surface next to smooth-matte surface. It is a desk ornament, a child's toy, and a small argument for smarter material allocation in product manufacturing.

"The best toy is the one that a child picks up without being told to — and that an adult quietly keeps on their desk for years without explaining why."
— Vespoo design brief
Inspired by the All-Wood Toy Scooter
The market for premium wooden toys is rich — Scandinavian brands, Japanese makers, small European workshops — and the wooden push scooter is a recurring form in all of them. These toys are beautiful. They are also slow to produce: each part individually turned or CNC'd from solid wood stock, assembled by hand, and priced accordingly.
The ambition for Vespoo was not to replace these objects but to learn from them. Keep the warmth, the weight, the satisfying material contrast — and redesign the production logic so the toy can be made more efficiently, with less offcut waste, and opened up to more colour options than wood stain and paint allow.
The scooter form was chosen deliberately. The Vespa silhouette is one of the most recognisable outlines in the world — a gestural shorthand that a child identifies in two seconds and an adult appreciates for the rest of their life.
Print what needs to be complex. Cut what can afford to be simple. Waste nothing.
Kids 3 and up, and every adult who deserves something nice on their desk.

Parts Breakdown — What Gets Printed, What Gets Cut
Body Frame
The main chassis and front fairing — the most complex geometry on the toy. Printed in PLA, available in any colour. The curved surfaces and integrated snap-fit pegs would be prohibitively expensive to CNC.
Wheels × 2
Perfect circles cut from a birch plywood sheet. Routing discs is one of the most efficient CNC operations — near-zero setup waste, maximum yield per sheet, and the natural edge grain adds warmth to the toy.
Seat
A simple convex plank profile routed from the same birch sheet as the wheels. The wood contrast against the coloured body is intentional — warm, tactile, and immediately legible as a seat.
Handlebar
A T-shaped piece cut from 6mm birch. The horizontal bar slots into a groove on the 3D printed neck — no glue, no hardware, just a tight friction fit that can be disassembled and reassembled by hand.
Headlight
A small round disc pressed into a printed recess at the front of the fairing. Adds a period-correct detail that references the round headlamps of classic Italian scooters.
Axle Pegs × 2
Short barrel pegs that pass through the wheel centres and snap into the body frame. Printed with a slight interference tolerance — firm enough to hold the wheels upright, loose enough to let them spin freely.
Vespoo vs Traditional All-Wood Toy
| Attribute | All-Wood Toy | Vespoo (Hybrid) |
|---|---|---|
| Complex curves | Hand-carved or multi-axis CNC — slow, expensive | FDM printed — fast, cheap, any geometry |
| Round parts (wheels, discs) | Lathe-turned or multi-pass CNC | Single-pass CNC rout — maximum sheet yield |
| Material waste | Significant offcut from solid wood blanks | Near-zero: additive for 3D print, efficient nesting for CNC |
| Colour options | Limited to paints and stains over wood | Any PLA colour on printed parts, natural wood fixed |
| Assembly | Often glued or pinned — permanent | Snap-fit and friction — fully reversible |
| Price point | High — labour and material-intensive | Lower — streamlined dual-process production |
Design & Visualisation Process
Reference & Market Study
Studied existing wooden toy scooters — particularly push-toy ranges by Scandinavian and Japanese makers — to understand what makes them compelling: the warmth of wood, the satisfying heft, the simple silhouette. Then mapped the production constraints: hand-crafted wooden toys are slow and expensive to make at any real volume.
Concept & Part Rationalisation
Broke the toy down into its constituent forms and asked: which parts genuinely need the freedom of 3D printing, and which can be cut far faster from sheet material? The rule that emerged — print the complex curves, cut the simple rounds. This split also produces the two-tone material palette as a natural outcome, not a stylistic add-on.
CAD & Tolerancing
Modelled the full assembly in Fusion 360. The snap-fit system was the hardest part to get right — tolerances that work across different printers and humidity conditions. Settled on a 0.3 mm radial clearance for the axle pegs and a 0.15 mm press-fit on the handlebar groove after three rounds of test prints.
Visualisation in KeyShot
Imported the CAD geometry into KeyShot for photoreal rendering. The birch wood texture and the matte PLA finish were the two material goals — warm, slightly rough, tactile. Multiple colour studies were run (red, olive green, slate blue, mustard) to evaluate how the body colour reads against the natural wood. Red and olive were selected for the final presentation.
Prototype & Assembly Test
Printed the body parts on a standard FDM printer and cut the wood components from a 3mm birch sheet. First assembly took under four minutes with no tools. The scooter sits stably on any flat surface, wheels spin, and the toy survives the drop test that every children's product dreads.
Renders
Rendered in KeyShot. The birch material was built from a procedural wood shader with custom grain direction matched to how the CNC cuts would run on a real sheet. Hover over each image for notes — click to enlarge.
Reflections & Takeaways
Process Defines Aesthetic
The two-tone look of Vespoo was never a stylistic decision — it is a direct readout of the manufacturing logic. Letting the process drive the palette produced something more coherent than any mood-board could. It is the most honest design outcome of the project.
Tolerancing is the Product
A toy that does not assemble cleanly is not a toy — it is a frustration. More time was spent on the fit of axle pegs and handlebar slots than on anything else. The rule: print a test peg before you commit to the full body. Save two days of re-printing.
KeyShot Reveals What CAD Hides
The material contrast between PLA and birch was obvious in person but difficult to judge in Fusion 360's viewport. Running colour studies in KeyShot early in the process — before committing to a print colour — would have saved one full round of prototyping. Visualisation is not just for presentation; it is a design tool.
Simple Toys Earn Their Complexity
Vespoo looks simple. Getting it to that point was not. Every dimension was driven by a constraint — shipping flat, surviving a drop, fitting a child's hand, being satisfying to spin the wheels on. Simplicity in toys is always earned, never assumed.
