From a photo, a sketch, or a broken part — to a finished part in your hand.

Custom 3D modelling and printing based in Geelong, serving Melbourne and regional Victoria. Send whatever you've got — a broken component, a drawing, or just a rough idea — and get a fixed quote back, usually the same day.

01 — Services

Three ways we turn an object into a part

You don't need a CAD file to start. If you can photograph it, sketch it, or hand it to us, we can model it.

A

Replacement & discontinued parts

A knob, bracket, gear, clip or housing that broke and isn't sold anymore. We reverse-engineer it from the broken piece or a photo with measurements, then print a working replacement.

B

Custom parts from your drawing or idea

Have a drawing, a napkin sketch, or a concept? We turn it into an accurate 3D model — jigs, fixtures, enclosures, mounts, prototypes — and print it in a material that suits the job.

C

Short-run functional printing

Already have a model? Send your STL or STEP file and we'll print it in PLA, PETG or flexible TPU, with the finishing and tolerances the part actually needs.

02 — Process

How it works

Step 1

Send what you have

A photo, sketch, drawing, or the broken part itself — plus any rough dimensions. Email or a quick text is fine.

Step 2

Get a fixed quote

We reply with a firm price and a lead time, usually the same day. No account, no waiting on a callback.

Step 3

We model, print, deliver

Approve the quote and we build the model, print it, check it fits, and get it to you — pickup or post.

03 — Capability

What the workshop does well

  • MATERIALSPLA for prototypes and light-duty parts, PETG for tough functional parts, and flexible TPU for grips, pads and seals.
  • SIZEParts up to roughly 220 × 220 × 250 mm in a single piece; larger jobs split and joined.
  • BEST FORFunctional mechanical parts — brackets, housings, jigs, fixtures, replacements — where fit and strength matter more than a glossy finish.
  • TESTINGA prototype is printed and test-fitted before any final part is committed. Where it helps, simulation is run to show direction early, then confirmed on the real part by test fitting. Destructive testing, loading and impact, can be arranged for smaller parts at small scale.
  • YOUR FILESSend us a file and it stays yours. Pay us to model a part and the model comes with it — you are not tied to us to have it made again. How this works.

Functional-grade FDM printing, with fit proven on a real part: we prototype, test-fit and adjust before the final part is made. Every quote includes an assessment of the duty, so where a part belongs in metal you get that recommendation at the quote.

Running collaborative robots? Custom gripper jaws and EOAT, made locally.

Part-specific fingers and end-of-arm tooling for Universal Robots, Robotiq and OnRobot setups — designed to your part, printed fast.

Three ways into the workshop

Replacement & discontinued parts

Broken or no longer sold — we reverse-engineer it and print a working replacement.

Jigs & fixtures

Workholding, drill guides and alignment fixtures, cheap to print and cheap to iterate.

Cobot gripper jaws & EOAT

Custom gripper fingers and end-of-arm tooling for Robotiq, OnRobot and UR setups.

05 — Explore by service

What the workshop actually does

Each one covers what the service involves, what to send when you enquire, and how the material and process get chosen for the job.

Reverse engineering

No drawings and no supplier? The part you have is the drawing. We measure it, model it and print it.

Obsolete machine parts

A machine down for a component nobody sells any more. Remade rather than replaced.

Prototyping & iteration

No tooling, no minimum quantity — so being wrong costs a reprint instead of a change order.

Short-run production

Repeat batches from a kept model, with a firm lead time agreed at the quote.

PLA, PETG or TPU?

What each material is genuinely good at, and how the right one gets chosen for your part.

Real jobs, written up

Every part below came from an actual job. Each has a page describing what arrived, what had to be worked out, and what went back.

Scroll sideways → or swipe

3D printed planetary gear set with an outer ring gear, three planet gears and a central sun gear, printed fully assembled in white filament on a green cutting mat

Planetary gear set

A print-in-place gear train for a university robotics project. The file had no running clearance between the teeth, so it was adjusted, printed and tested twice.

White circular housing with three mounting lugs, a ring of counterbored holes around a finely ridged inner ring, and a large central bore White circular bearing plate with a stepped profile, central bore, ring of holes around it, and hand-drawn pen marks on the face

Cycloidal gearbox — housing and front flange

A robot arm builder sent an STL and asked for a larger gearbox. Scaling it meant re-deriving every feature that mates with a bought bearing or fastener. Two complete sets printed.

Red cylindrical housing with an open bore, a side outlet spout and two flanged feet with mounting holes Five black 3D printed pump parts laid out on a steel ruler: a cylindrical housing with mounting lugs, a round cover plate, a small vaned rotor, a shaft support and a plate with a central hole

Mini centrifugal pump — housing and full assembly

Modelled from scratch — no file, no part to copy — and designed so the customer could print the whole assembly on their own machine.

White cylindrical motor housing for a hobby robot, open at one end, with a smaller cylindrical boss projecting from one side

Robot motor housing

The customer's own design and a good file. Their machine kept failing halfway through the long run, so it was printed here in one go.

Flat white plate in an H shape with two holes at each end

Industrial mount prototype

One of many prototypes of a mount for an industrial client. The plainest part on this page, and the longest-running job.

07 — Who this is for

Built for businesses and workshops

The work suits an organisation with a part that has to function — measured, modelled, prototyped and test-fitted before it is called finished.

A good fit

Machines with obsolete parts and no supplier left. Jigs, fixtures and production aids for one specific job. Gripper jaws and end-of-arm tooling for a cobot cell. Mounts and brackets developed over several rounds. Short runs of a part you will need again. Prototypes that have to exist before a decision can be made.

Minimum order $75

How the approach gets chosen

Tell us what the part does, what it touches and where it lives, and the material, wall thickness and print orientation are decided from that — PETG for tough outdoor work, PLA for accuracy under light load, flexible TPU for anything that grips or seals. Where a part would be better made another way, you get that recommendation at the quote, when it is still worth having.

How materials are chosen →

The five jobs written up here cover an industrial client, a business one-off, a university project and two people building something themselves. Send a photo of yours and you will have a price, usually the same day.

Send a photo. Get a price.

The fastest way to a quote is a photo of the part or drawing, with a rough size — and tell us the machine or assembly it's for, because that usually decides the material and the print orientation before anything else. We reply the same day where we can. Minimum order $75. Based in Geelong, serving Melbourne and regional Victoria — pickup or Australia-wide post.
