WE GLOW UP / IN-HOUSE PRODUCT DEVELOPMENT

Wave.
Space between the teeth.

A wide-tooth comb developed around a simple brief: more space between the teeth, a distinctive silhouette and a single-material bone-white finish.

THE BRIEF

Give an everyday object its own identity.

We developed Wave as an in-house We Glow Up project. The brief asked for wider tooth spacing and a recognisable shape, while keeping the comb practical to manufacture as one flat 3D print.

The design evolved from a closer-spaced first iteration into thirteen broad, rounded teeth beneath an asymmetric wave spine. A thumb saddle, integrated oval hanging loop and recessed “we glow up” lettering complete the form.

8.8 mm clear gaps

The straight working section has twelve 8.8 mm gaps, increased from 4.8 mm in the first iteration. The rounded roots blend into the spine.

180 × 74 × 6 mm

A compact, one-piece body with 5.6 mm wide teeth, rounded tips and a gently curved tooth-tip line.

One material

Prepared for bone-white PETG with recessed, uncoloured branding. The flat print orientation requires no supports in the supplied setup.

From brief to printable geometry.

  1. Refine the formDevelop the spine, tooth spacing, rounded tips and hanging loop.
  2. Build editable CADCreate the solid model and export STEP and STL files using a CAD and scripting workflow.
  3. Check the exportVerify a valid CAD solid, one watertight mesh and thirteen teeth with twelve 8.8 mm gaps.
  4. Prepare a prototypeSlice for a P1S with a 0.4 mm nozzle and prepare a smaller tooth-spacing test piece.

What the project demonstrates.

Shape development, dimensional CAD, integrated branding, model validation and preparation for a single-material FDM print.

The full-comb slice estimates 40.9 g of PETG and 2 hours 34 minutes including startup. These are slicer estimates, not a production quote. The images are CAD renders; comfort, hair snagging, durability and cleaning performance still require physical evaluation. No salon-performance or reduced-breakage claim is made.

This is our own product development, supported by CAD, scripting and AI-assisted tools. It is presented as a portfolio project, not as a commissioned client result or an item currently offered for sale.
