How to make a 3D printed cake topper
A custom cake topper costs $15–30 and takes days to arrive. Printed at home it costs pennies in filament and is ready in an hour or two.
The only obstacle used to be the file: printing needs an STL, and creating one meant learning 3D modelling. This generator removes that step — type the text, pick a font, download the file.
Tips for cake toppers that do not snap
Cake toppers are thin and long, so they break easily with the wrong settings. What matters most:
- Depth: 4–6 mm. Below 3 mm the piece warps and cracks when pushed into the cake.
- Layer height: 0.16 mm balances speed and clean letter curves.
- Infill: 10–15% is plenty for a decorative piece.
- Brim 4–5 mm: essential. Letters have a small footprint and lift without it.
- Print flat, text facing up. Vertical needs supports and shows layer lines on the visible face.
