How to make 3D printed classroom labels

2 July 2026 · 5 min read

Printed labels are far tougher than paper and look smart on trays, pegs and doors. Here’s how to make a consistent, hard-wearing set for a classroom.

Legibility comes first

Labels are read quickly and often from a distance, so a bold sans such as Poppins Bold beats anything decorative. Keep to one or two short lines — a name or class over an area — and give the text room to breathe.

A consistent set

A set looks intentional when every label shares the same font, backing shape and colour. Pick a school colour for the backing and white for the lettering, and keep the sizes uniform across the batch.

  • Two short lines at most — long names shrink and get harder to read.
  • Add mounting holes for pegs and doors; leave them off for stick-on tray labels.
  • Making a whole class? Bulk generate turns a list of names into a matching set (Pro).

Keep names short and the strokes bold; the printability check will warn you if lettering is too fine to survive classroom use.

Durability for daily use

PLA is fine indoors, but PETG copes far better with knocks, drops and wiping down — a sensible choice for trays and pegs that get handled all day. Rounded corners and a slightly thicker backing help too.

Step by step

  1. 1
    Choose the Wall sign mode

    You get a solid backing with optional mounting holes for pegs and doors.

  2. 2
    Type two short lines in a bold sans

    A name or class on top, an area or room underneath — keep both brief.

  3. 3
    Pick a school-colour backing with white lettering

    High contrast keeps labels legible across the room.

  4. 4
    Set the mounting and check the strokes

    Add screw or hanging holes where needed and confirm nothing is too thin.

  5. 5
    Export and print in PLA or PETG

    PETG lasts better on trays and pegs that get handled every day.
