"Best / Teacher" in two lines of a friendly handwritten script, cut out around the words, white letters raised on a green outline. Teacher appreciation gifts are one of the biggest keychain occasions of the year, and this one is small, personal and actually gets used on a lanyard or a classroom key. Good for the end of the school year, Teacher Appreciation Week, Christmas and a teacher's birthday.

Made with our free keychain generator, not modelled by hand: we typed "Best" and "Teacher" on two lines, chose the Letter outline shape and the Casual Script font, set the text size to 11 mm and the border to 4.5 mm, and picked the two colours. The zip holds exactly what the tool downloads: a 3MF with the tag and the raised letters as two coloured parts, and a one-piece STL. It comes out 54 by 33 mm and 4 mm thick, and prints flat with no supports.

Tie it to a thank-you card signed by the class. A kid who helped print it will tell the teacher all about it. Printed in one colour it still reads, because the letters stand proud of the tag; for green and white, a single-nozzle printer needs one filament change, and the print sheet in the zip says where.

Shown as a 3D render of the printed keychain with a steel split ring, not a photo.

What you need

2
  • About 4 g of PLA or PETG, in green and white
  • A split ring or keyring, about 25 mm across

How to make it

4

  1. Print it flat as exported: no supports, 0.4 mm nozzle, 0.2 mm layers.

  2. Multi-colour printer: open the 3MF, each part already carries its colour. Single nozzle: add a filament change in the slicer's layer preview for white at 3.3 mm above the bed.

  3. Let the bed cool before you lift the tag off, so the thin edges stay flat.

  4. Open the split ring with a thumbnail or a small screwdriver and wind it through the hole.

Questions about this design

Is the Best teacher keychain a good end-of-year gift?

Yes, and a classroom favourite: it is personal without being a mug, it fits on a school lanyard, and it costs a few grams of filament. Print one per teacher and teaching assistant and hand them over with the class card.

Can I write Best Coach or Best Nurse on the Best teacher keychain?

Yes. Open the free keychain tool, choose Letter outline and the Casual Script font, and type Best on the first line and Coach, Nurse, Mentor or Boss on the second. The outline follows the new words automatically.

Where do I change filament to print the Best teacher keychain in 2 colours?

Start in green, then change to white at 3.3 mm above the bed. Those heights are measured in the file, from its lowest point, which is where your slicer puts the bed; add each change in the layer preview where the new colour first shows. With a multi-colour printer, skip all that and open the 3MF.
