This 3D printable smiley stencil ruler combines a simple ruler with a set of different smiley templates. It’s designed for anyone who likes to give quick visual feedback, organize notes, or add a bit of personality to notebooks and worksheets.

You can use it to mark homework, highlight moods, decorate journals, or simply draw clean and consistent smileys without freehand drawing. It works well with pens, markers, and pencils and can be reused as often as you like.

Teachers may find it helpful for quick feedback in class, but it’s just as useful for students, parents, journal users, or anyone who enjoys neat and practical stationery. 

Instead of using stickers or stamps, this stencil gives you an easy and reusable way to draw neat smileys in seconds.

The design is lightweight, and fits nicely into most pencil cases. No supports are needed, and it prints well in common materials like PLA or PETG.

👉 There is also a second print profile available that includes only the smiley stencil, without the ruler, for those who prefer a more compact version or don’t use an AMS.

If you print it, feel free to share your result and let me know how it works for you. 😊

Happy printing!
