A tag that does something when a phone taps it — puts the phone in sleep mode by the bed, shares the guest Wi-Fi, opens the manual, calls you if a bag is found. Any shape, any word, chip sealed in and programmed. Previewed live in 3D, printed to order in Melbourne.
Engraved reads crisper at small sizes (great for names) and takes a colour-fill nicely. Raised stands proud for a chunkier look.
Bambu Lab PLA Basic filament colours — the preview shows a matte-PLA render of your pick. Preview colours only; the exact filament shade can vary slightly from the render. Two-colour lettering is an AMS finish — tell us in the order notes.
The chip is sealed in the back of the tag. Tap a phone on it and it does what you chose: an automation (iPhone Shortcuts or Home Assistant run on the tag itself — no data needed, so a bedside tag can put the phone in sleep mode), a link, a call or an SMS. We program it before shipping; change it any time with a free NFC app. 25 mm round or 21 × 11 mm rectangular NTAG213 in stock, included.

Split-ring hole is Ø4 mm with a solid 3 mm+ loop so it won't tear. NFC chip pocket adds A$2 — 25 mm round or 21 × 11 mm rectangular NTAG213 in stock, programmed before shipping. Made to order in 3–5 days. No licensed logos or characters.
Made in this studio and printed in Melbourne on a Bambu Lab printer, no post-processing: a FORMADA3D keyring tag (Jade White PLA, lettering raised in Cobalt Blue) and the NFC set — Tap-to-Pay and Tap-for-Wi-Fi plaques, a sleep-mode disc and a kids bag keychain tag, each with the sealed chip and the red NFC INSIDE mark on the back.

A solid one-piece plate — 3–6 mm thick — with your name, shape or logo either engraved into the face or raised proud of it, and a reinforced Ø4 mm split-ring hole so it clips straight onto keys, a bag, a backpack zip or a lunchbox. No assembly, nothing to glue. Interior counters of letters like O, A and e stay as clean through-holes. Every tag carries a 45° chamfer, 0.8–1.0 mm, on the top edge — it takes the slab look off the plate and catches the light like a moulded part. It is on the top face only, so the tag still prints flat on the bed with no supports.
Tick Add NFC chip and the tag is built around a sealed cavity — Ø25.6 × 1.0 mm at z 1.2–2.2 mm, sized for the 25 mm NTAG213 sticker we keep in stock (the default — we program it before shipping). There is no open pocket on either face: 1.2 mm of PLA under the chip, 1.8 mm over it on a 4 mm tag, and 2.5 mm of tag all round it, clear of the split-ring hole and the keyring lug. The studio raises the size for you if the tag is too small (and holds the thickness at 4 mm minimum, which is what the sealed stack needs), and tells you when a shape is too narrow. A phone reads it straight through the plate.
How the chip gets in — the print pause. The printer runs a pause at layer 7 (z 1.2 mm, 0.2 mm layers): it stops with the cavity floor exposed, the NTAG213 sticker is dropped in, and the print resumes and closes it over. Same method as our Pet ID tags. Printing it yourself from one of our free STL files? Set the pause at layer 7 in Bambu Studio (or your slicer's "Add pause" at z 1.2 mm) before you slice — otherwise the cavity prints closed and empty. No supports: the cavity roof is a 1.0 mm internal bridge that self-supports in PLA, and the tag's 45° edge chamfer is on the TOP face only, so layer one is full width.
