Started from

The client's worn original part

Quantity

A single replacement

What we brought

What we can do

We model a part from the worn original

We measured the old latch arm and modelled every notch, rail and step in CAD from the part itself.

How we look after you

One part is worth making

A single replacement is a normal job for us, with no minimum order and no tooling to pay for.

What you get

A copy shaped like the original

The printed arm carries the same profile, notches and square catch as the original, ready to go back in.

The brief

Step 1 of 5

Starting point: The worn original latch arm
Quantity: One

At Additive Inn, our 3D printing studio in Singapore, we make one-off replacement parts. A client needed a new latch arm for their motorcycle box, copied from the worn original so it would fit and lock the same way.

Measuring and modelling

Step 2 of 5

We measured the original arm and rebuilt it in CAD: the long notched arm, the raised rails along it and the square catch at one end. The model let us check every slot before printing.

Production

Step 3 of 5

We printed the new arm in one piece in black on our FDM printers, laid flat so the long, thin arm stays straight along its length.

Finishing and checks

Step 4 of 5

We cleaned up the print and checked it against the original, matching the notches, rails and catch so the arm would slide and lock as before.

Step 5 of 5

The client received a replacement latch arm shaped like the original, ready to go back into their motorcycle box.
