3D Printed Locker Name Tags
For lockers, cubbies and shelves
Type a name and the generator puts an outline plate behind the letters, so each locker tag is one solid piece with a flat back for magnets or tape. Preview it for free, download STL or a two-colour 3MF, and a tag prints in 15 to 30 minutes.

Starts on Anton with an outline plate: bold, narrow letters that read from across a changing room. Capitals look best on a locker.
A locker tag that stays put
A locker name plate from this page is one flat part: the letters stand proud of a plate that follows their outline, 1.5 to 6 mm wide. The back is flat, so a magnet or a strip of tape covers it fully. It prints face up with no supports and weighs 5 to 15 g, which is why even small magnets hold it on a steel door.
Anton is the default because it's tall, narrow and heavy. A long name like ALEXANDER still fits a 100 mm tag, and the thick strokes survive being knocked by a bag every day. For younger kids, Baloo 2 is rounder and friendlier.
Sizes for lockers, cubbies and shelves
Scale the file in your slicer. The tag width follows the name, so set the letter height and let the rest fall into place.
| Where | Tag width | Letter height | Typical print |
|---|---|---|---|
| School or gym locker door | 80 to 120 mm | 18 to 25 mm | About 20 min, 5 to 8 g |
| Cubby or coat hook | 60 to 90 mm | 15 to 20 mm | About 15 min, 4 to 6 g |
| Staff locker, workplace | 70 to 100 mm | 15 to 20 mm | About 15 min, 5 g |
| Shelf edge or storage bin | 50 to 80 mm | 12 to 15 mm | About 10 min, 3 g |
PLA at 0.2 mm, thickness 4 to 6 mm, on a Bambu Lab A1 mini or similar. Ten locker tags fit on one 180 mm plate and print in about 2 to 3 hours together.
Magnets, tape or screws
Glued magnets (easiest)
Glue two 8 x 2 mm or 10 x 2 mm neodymium discs to the back of the widest letters with two-part epoxy or CA glue. Steel locker doors hold that easily, and the tag moves when the locker changes owner.
Flexible magnetic tape
Self-adhesive magnetic strip, cut to the tag length. Weaker than neodymium, but safer around small children and cheap for a whole class.
Double-sided tape
For wooden cubbies, plastic lockers and painted shelves. Foam tape for permanent, removable strips if the tags change every school year.
Screws
For a nursery coat rack or a workshop wall. The generator has no holes, so drill a 3 mm hole in the plate after printing, at low speed.
Embedding magnets with a pause at height
A magnet sealed inside the print looks cleaner and can't be picked off. The generator doesn't cut magnet pockets, so you add one in the slicer.
- 1
Make the tag thick enough
Set thickness to 8 mm or more. The plate is 40% of the letter thickness, and the pocket goes under the letters, where the part is thickest.
- 2
Add a pocket
In Bambu Studio, OrcaSlicer or PrusaSlicer, add a negative cylinder 0.2 mm wider and deeper than the magnet, under a wide letter, starting about 0.6 mm above the bed.
- 3
Pause at the right layer
Add a pause at the first layer above the top of the pocket. Check it in the layer preview: the pocket should be open, the next layer should close it.
- 4
Drop the magnets in
When the printer pauses, press the magnets in. Mark the polarity if the tag goes on another magnet; for a steel door it doesn't matter.
- 5
Resume
The printer closes the pocket and finishes the letters. The thin skin on the back costs a little pull, which a steel door doesn't notice.
School, gym and workplace
School lockers
One colour per class or house, white letters on a coloured plate. For every student, see the bulk name tags workflow.
Gym and sports club
Team colours, names in capitals, magnets so tags swap between seasons. Add a number on a second row.
Workplace lockers
Staff lockers, tool cabinets and hot desks. Plain black on white in Roboto or Oswald looks tidy. A desk name plate matches for the office side.
Home and nursery
Cubbies, toy bins and coat hooks. Tape or screws rather than loose magnets where toddlers can reach.
A word on magnets and small children
Small neodymium magnets are dangerous if swallowed, especially two at once. For anything a young child can reach, seal the magnets inside the print with the pause method above, or use tape or screws instead. The generator makes text only, so for kids who can't read yet, add a sticker or a symbol next to the name. For more classroom setups, see the 3D printing classroom project.
Questions people ask
How do I 3D print a locker name plate with a magnet?
The easy way is to glue two small neodymium discs to the back with epoxy. For a hidden magnet, add a pocket in your slicer, pause at the layer that closes it and drop the magnets in. Set thickness to 8 mm or more so there's room.
What size should locker name tags be?
About 80 to 120 mm wide with letters 18 to 25 mm tall for a school or gym locker. Cubby labels are fine at 60 to 90 mm.
Can I make name tags for a whole class or team at once?
Yes. The Unlimited plan exports up to 100 names as one ZIP. See pricing.
Which font is best for locker labels?
Anton for bold capitals that read from across the room, Oswald or Roboto for a plain workplace look, Baloo 2 for younger kids.
Can I print the tags in two colours?
Yes. The 3MF puts letters and plate on separate filament slots, so an AMS prints both colours without setup. On a single nozzle, add a filament change where the letters start.
Can I sell locker tags or cubby labels?
With a subscription, yes. Unlimited includes commercial use. A single download is for personal use only.
