CAD MODELLING AND 3D PRINTING SERVICE
At TechneCAD, I provide high-quality CAD modelling, product design, and 3D scanning and printing services for individuals and small businesses. Whether you need a prototype, a custom part, or a full design from concept to manufacture, I combine engineering expertise with modern design tools to deliver accurate, reliable results.
I work with clients across automotive, aerospace, mechanical, consumer products, and hobbyist projects, all across Melbourne. Offering everything from reverse-engineering and design optimisation to fast, affordable 3D-printed parts.
Services
If you’ve got an idea, a broken part, or a project that needs engineering support – I can help bring it to life quickly and professionally.
CAD & Engineering Drawings
Parametric 3D models, engineering drawings, assemblies, mechanical design, and production-ready drawings.
3D Printing
High-quality prints, small-batch manufacturing and rapid prototyping in a range of materials and colours.
Design for Manufacture
Optimising parts for CNC machining, sheet-metal cutting, forming, fabrication, or injection moulding.
Reverse Engineering
Recreating or improving existing parts from a 3D scan, sketches, samples, or measurements of physical parts.
From Automotive to Aerospace, Electronics to Hobby Builds – I’ve designed parts for them all.
This snippet showcases my general workflow when designing parts via reverse engineering. Using a 3D Model of a Raspberry Pi 4 Model B as the baseline, I progressively design a protective case which can be manufactured rapidly via 3D Printing or in bulk via injection moulding.
CUstomer project #1
Custom 3D Printed RC Car Parts – Shock Mount Replacement & Upgrade
A customer needed replacement shock mounts for a damaged RC car. The original parts had failed and weren’t easy to replace, so instead of trying to source new ones, we rebuilt them from scratch.
Using 3D scanning, manual measurements, and CAD modelling in SolidWorks, I recreated both the front and rear shock mount assemblies to fit the existing setup.
Rather than copying the original design exactly, I strengthened the weak points that typically fail:
- Added reinforcement around stress areas
- Increased thickness where the original parts cracked
- Improved overall support to handle repeated impacts and jumps
The final parts were 3D printed using durable materials suited for RC use, where vibration, crashes, and rough terrain are constant.
End result: a set of replacement parts that fit properly and hold up better than the originals.
CUstomer project #2
Custom Stainless Steel Trailer Undertray Toolbox – Bespoke Storage Design & Build
Customer provided a concept drawing for a pair of undertray toolboxes to mount on a trailer, one for the driver side and one for the passenger side. The job was to convert the sketch into a fully defined, manufacturable design that could be fabricated by a local machine shop.
Using the customer’s initial dimensioned hand drawing as a reference, I developed both assemblies in CAD, ensuring correct fitment under the trailer chassis while accounting for clearances, mounting points, and access to the doors. The design was structured to be practical for fabrication, transport, and installation.
Key things to consider included:
- Conversion of the sketch into accurate 3D models and fabrication-ready geometry
- Design of front-opening doors with integrated compression locks for secure closure
- Optimisation of panel layouts for flat pattern development and laser cutting
- Provision of bend allowances and fold lines suitable for sheet metal manufacturing
- Ensuring both driver and passenger side boxes were mirrored correctly while maintaining consistency in mounting and usability
My services included detailed CAD models, DXF flat patterns for laser cutting, and dimensioned drawings to guide bending and assembly. These were supplied to the customer, who then coordinated with a fabrication shop to have the components laser cut from sheet material and formed according to the provided drawings.
End result: a matched pair of undertray toolboxes that aligned with the trailer design, were straightforward to manufacture from the supplied files, and provided secure, practical storage with a clean, integrated fit.

CUstomer project #3
Custom 3D Printed ESP32 Enclosure – PCB Housing for In-Car Waze Traffic Alert System
A customer was building a custom GPS (Waze-based) traffic alert system using an ESP32, but needed a clean, secure way to house the electronics and mount everything inside a car. Off-the-shelf enclosures didn’t suit the layout or wiring, so a fully custom 3D printed housing was developed.
The project went through two design iterations. The initial version was built around a standard PCB layout, but was later scrapped when the customer moved to a custom PCB design. This required a complete redesign of the internal layout to suit the new board, mounting points, and wiring configuration.
Starting from the updated components, I created a space claim around the PCB, wiring, and speaker to ensure everything fit without interference. The enclosure was then designed to keep components secure while staying compact enough for an in-car setup.
Key features of the final design:
- Dedicated custom PCB layout slots for mounting
- Clearance for wiring and connectors to prevent strain
- Integrated speaker housing, allowing sound to pass through clearly
- Openings for LED visibility so alerts can be seen easily
- No mounting hardware for assembly, a snap-lock system was developed
The enclosure was 3D printed in PLA and designed to protect the electronics while still allowing sound and light output where needed.
End result: a compact, purpose-built housing that fits the updated electronics properly, mounts cleanly in the car, and turns a loose prototype into a usable, finished system.
FAQs
How does pricing work for your services?
Each project is quoted individually based on its complexity, requirements, and expected time involved. Once you share the details of your job, I’ll assess the scope and provide a clear, personalised quote before any work begins. This ensures you only pay for what you need and there are no surprises.
What information do I need to provide to get a quote?
To prepare an accurate quote, I’ll need a brief description of your project, any sketches or reference images, measurements, and the intended use of the part. The more detail you can provide, the faster and more accurate the quote will be.
How long does a typical project take?
Lead times vary depending on the complexity and size of the job. Simple models can often be completed within a couple of days, while more detailed or technical projects may take longer. I’ll give you an estimated timeframe when I provide your quote.
Can you work from sketches, broken parts, or existing models?
Yes. I can work from rough sketches, photos, samples, or existing 3D files. If you have a broken part, I can reverse-engineer it and create a digital model for repair or reproduction.
Do you do revisions if I need changes made?
Absolutely. Revisions are part of the process. Minor adjustments are usually quick, and any major revisions will be discussed before work continues so there are no unexpected costs.
What payment methods do you accept?
I accept bank transfer and PayID. For larger projects, a deposit may be required before work begins.
Do you create models for CNC, laser cutting, or sheet-metal work?
Yes. I can generate models and flat patterns for CNC machining, laser cutting, waterjet cutting, and sheet-metal fabrication. If you’re working with a specific manufacturer, I can tailor files to their requirements.
Do you provide design advice or help refine ideas?
Definitely. If you have an idea but aren’t sure how to turn it into a functional design, I can help refine it and suggest improvements based on manufacturability, strength, and material suitability.
What file formats do you accept and deliver?
I accept most standard formats including STEP, IGES, STL, and 3MF. Final files can be delivered in whatever format you need for 3D printing, manufacturing, or documentation.
Do you offer 3D printing as well as CAD modelling?
Yes. I offer both CAD modelling and 3D printing services. I can design, prototype, and manufacture your part from start to finish.
What materials can you print in?
I can print in a range of materials including PLA, PETG, ABS, ASA, TPU (flexible), and various engineering-grade filaments. If you’re unsure which material suits your application, I can recommend the best option.
Do you provide engineering drawings for manufacturing?
Yes. I can produce detailed engineering drawings suitable for machining, fabrication, or mass production. Drawings include dimensions, tolerances, and any necessary manufacturing notes.
Do you ship prints or offer local pickup?
Both. I offer local pickup, and I can ship anywhere in Australia. Shipping costs will be included in your quote.
