Sticky note
Printable now
A printed sticky note for the fridge or the desk, with a tap icon and an NFC sticker inside.
get the files: the notes on GitHub: open it in OpenSCAD’s Customizer, choose the Type, and export a 3MF. The Model Maker on MakerWorld once its listing is public.
The note you’d leave for the family (the Wi-Fi, who to call, when you’re back) as a tap you update from your phone, not a scrawl you rewrite.


- how it works
- Tap the tap icon: the sticker is under it.
- Today: it opens whatever you write to it, like any sticker: a link, your contact card, your guest Wi-Fi.
- Coming in the next app update, notes: write a note in Tilde (“Back at 6, dinner’s in the fridge”), then Write a sticker. A tap opens the note on a page, on any phone, with no app. To change it, edit it in Tilde and tap the sticker again.
- Anyone who taps it can read it.
- On the fridge: magnets in the back. On a desk: the cradle, or the thin back.
- use cases
- Guest Wi-Fi on the fridge: Android guests tap; iPhones scan a Wi-Fi code.
- A note for the family: for the sitter or the kids (coming in the next app update).
- Save my contact: the family’s numbers, as a contact card.
- A link: the school calendar, the takeout menu.
- pairs well with
- Grocery list: the same back, for the list.
- Calendar: the same family on the fridge.
- Wi-Fi coaster: guest Wi-Fi with a code iPhones can scan.

- Magnets: 10 × 2 mm, 3 for the large note (1 for the small).
- Glue: for the folded corner.

Grocery list
Printable now
A printed list for the fridge, handwritten-style (“milk, bread, eggs”), with an NFC sticker inside.
get the files: the notes on GitHub: open it in OpenSCAD’s Customizer, choose the Type, and export a 3MF. The Model Maker on MakerWorld once its listing is public.
The list on the fridge is never the one in your pocket.


- how it works
- Today: a tap opens whatever you write to the sticker, such as a link. Tilde doesn’t make lists yet.
- Coming in the next app update, lists: make the list in Tilde, then Write a sticker. A tap opens the list on a page with tick boxes, on any phone, with no app. Your ticks stay on your phone; they don’t change the list on the fridge. To update it, edit it in Tilde and tap the sticker again.
- It doesn’t sync: the list on the page is what’s on the sticker. Only its owner updates it, in Tilde.
- Anyone who taps it can read the list.
- use cases
- The shopping list on the fridge: tap it on the way out, and the list is on your phone (coming in the next app update).
- The week’s meal plan, the same way (coming in the next app update).
- pairs well with
- Sticky note: the same back and magnets.
- Calendar: the family’s fridge.
for makerswhat you need, sizes, options
- NFC sticker: 1 round 25 mm sticker, under the tap doodle (an NTAG216 holds a full contact card; an NTAG215 is fine for a link); anti-metal for the thick backs on a fridge.
- Magnets: 10 × 2 mm, 3.
- Glue: for the folded corner.
- Printer: three colors.
- Difficulty: easy.

- size and materials
76 × 102 mm (short 76 × 76); the face is 1.6 mm. PLA, about 28 g (tall).
