01 / What this service is

What this service is

Mechanical design and CAD covers the physical side of prototypes and products — from the enclosure your PCB lives in, to the bracket that holds it all together.
01

Enclosures & housings

Designed around your PCB and component stack — not the other way around. We build for assembly, not just aesthetics.

02

Brackets, fixtures & mechanisms

Structural and functional hardware — mounting, articulation, retention. Toleranced for the manufacturing process you're actually using.

03

Mechatronic / robotic mechanical design

Pragmatic and prototype-focused. We scope to what the product needs to prove — not research-grade precision for its own sake.

04

DFM — design for manufacture

DFM built into the design process, not bolted on at the end. Fewer revision cycles, fewer surprises when parts come back.

Important boundary

This is not civil engineering. Structural analysis for buildings, bridges, or load-bearing civil infrastructure sits outside our scope.

02 / Who it's for

Who it's for

Tap any card to flip it — front shows the fit, back shows why.

Good fit if

You need a prototype enclosure that can actually be built

Buildableflip →

— Why it fits

Not a render. A design toleranced for 3D printing, sheet metal, or injection moulding — whatever your production path is.

← back

You want DFM thinking early to avoid expensive rework

Cost reductionflip →

— Why it fits

DFM is baked in from the first sketch — not a last-minute review. Cheaper to fix a wall thickness at sketch stage than after tooling.

← back

You need mechanical design that integrates with electronics

Integrationflip →

— Why it fits

PCB clearances, connector positions, thermal management, and cable routing — designed alongside the electronics, not after.

← back
Not a fit if

Civil engineering — structures, buildings, infrastructure

flip →

— Why not

Structural analysis, load calculations, and certified civil work sit entirely outside our scope.

← back

Regulated medical device or manned aviation / aerospace

flip →

— Why not

These require specialist safety certification frameworks we're not set up for. We'll say so upfront.

Problems we solve

Click a problem to see the root cause and what we do about it.

"

Our prototype doesn't fit together reliably.

"

We need an enclosure that protects electronics and is manufacturable.

"

We need mechanism design that can be built and iterated.

"

We need CAD cleaned up and made production-ready.

"

We need DFM improvements to reduce cost and assembly time.

04 / Deliverables

What you receive

Click any tile to see what's in it and when it applies.

Always

CAD models

Native + STEP

Native format for your CAD tool plus universal STEP export — ready for your manufacturer or next engineer.

01+
If required

Drawings

Where required

2D engineering drawings with GD&T, tolerances, and surface finish callouts — wherever your supplier needs them.

02+
Always

Assembly guidance

Notes + instructions

Step-by-step assembly notes, torque specs, and sequence — so the build can be handed to someone who wasn't in the room.

03+
Always

Tolerance & fit checks

Stack-up analysis

Tolerance stack-up reviewed at assembly level — before parts are made, not after they come back wrong.

04+
Always

Prototype build pack

Fabrication + assembly

What to order, from where, in what order to build — a single document your team can follow without chasing us.

05+
If DFM in scope

DFM recommendations

Redesign outputs

Prioritised list of design changes — ordered by cost/assembly impact — with updated geometry where agreed.

06+

If the work includes electronics integration, we'll coordinate with PCB and enclosure constraints — deliverables scoped to match.

05 / Engagement modes

How we engage

Three paths depending on how defined your scope is. Click an option to see outputs and timing.

A

Quick CAD / DFM audit

Paid sprint style

Best when

You have existing CAD and want a clear, prioritised plan to improve it — without committing to a full redesign first.

Outputs

Prioritised fix list — ordered by cost / assembly impact

Redesign approach for top issues

Estimate range for implementation (where possible)

B

Fixed scope CAD pack

Defined deliverable set

Best when

Deliverables are already clear — e.g. enclosure redesign, bracket set, mechanism. Scope agreed upfront, delivered to spec.

Outputs

Full CAD model (native + STEP)

Engineering drawings where needed

Build pack — what to fab, how to assemble

C

Milestone-based mechanical design

Iterative delivery

Best when

Constraints evolve and iteration is expected — design is staged across milestones with review and sign-off at each gate.

Outputs

Staged design milestones with review gates

Evolving CAD updated each stage

Risk log and open items tracked throughout

Minimum engagement

06 / Tools & stack

Tools & stack

Mainstream CAD tools, exchangeable formats. Toolchain confirmed during discovery. Click a category to see tools — hover a tool for context.

Fusion 360

Default — parametric, cloud-collaborative, DFM features built in

FreeCAD

Open-source alternative where client toolchain requires it

STEP / STP

Universal — every supplier and downstream engineer can open it

DXF / DWG

2D drawings and laser / waterjet cut profiles

STL / 3MF

3D print-ready exports for rapid prototype runs

FEA (Fusion)

Static stress and deflection — enclosures, brackets, fixtures

Tolerance analysis

Stack-up review before committing to manufactured parts

Engineering drawings

GD&T annotations, tolerances, and finish callouts

BOM

Bill of materials — part numbers, quantities, supplier references

Assembly instructions

Sequence, torque specs, and build notes

Toolchain and file formats confirmed during discovery — always matched to your supplier and downstream workflow.

07 / Relevant work

Relevant work

Published with permission — many can be anonymised. Click a row to see the before and after.

Before

Prototype enclosure with 14 design issues flagged by manufacturer — tooling cost estimate was 40% over budget.

After

Wall thicknesses corrected, draft angles added, snap-fit redesigned. Tooling quote reduced significantly after redesign.

14

issues resolved before tooling

Before

Wearable device needed enclosure designed around an existing PCB — with a folding mechanism and two-part housing.

After

Full CAD pack delivered: enclosure, folding mechanism, tolerance study, and build instructions ready for 3D print run.

08 / Quality

How we keep quality high

Quality you can see, not just trust. Hover any row to see what makes it visible.

Clear requirements & acceptance criteria

Fit, function, constraints

Requirements brief agreed and signed off before any CAD begins. Fit, function, and manufacturing constraints all captured — so rework is a choice, not a surprise.

Design review and risk tracking

Interference, tolerances, assembly

Assembly interference checks, tolerance stack-up review, and a shared risk register — updated at each stage, visible to you throughout.

Prototype validation notes

Where applicable

Test notes documenting what was validated, what wasn't, and known edge cases — included in the handover so the next engineer knows what the prototype proved.

Build-ready handover pack

CAD, drawings, BOM, instructions

STEP files, engineering drawings, BOM, and assembly instructions delivered together — structured for a manufacturer or next engineer who wasn't in the room.
