MP-01 — APPLE WATCH ULTRA, RE-CASED
The Smallest Phone You Own.
Your Apple Watch Ultra already makes calls, sends messages, navigates and pays. The MP-01 takes it off your wrist and bolts it — six M3 screws, brass inserts, carbon-fiber nylon — into a pocketable mini phone. Everything you need. Nothing that feeds.
FIELD MANUAL — 01
Leave the Phone.
Keep the Signal.
The average phone gets picked up 144 times a day. Almost none of those pickups are the call, the route or the payment — they are the feed. A cellular Apple Watch Ultra carries every function you actually leave the house for, with a screen too small to scroll and too honest to lie to you.
The MP-01 finishes the argument. Two carbon-nylon plates bolt the Ultra into a handheld the size of a matchbox: display framed flush, crown and action button free, speaker open, charging through the back. No clips that give up, no silicone that stretches. Six screws — it goes in a pocket, a pack lid, a chest rig.
The CAD is public — STL files ship on the product page.

THE SIDE SHOW
AT-02 Tag Case.
The AirTag, Armored.
The AirTag, armored. Six bolts, an integrated lanyard slot, zero chance of popping out. Same chamfers, same bolts, same carbon-nylon as the MP-01 — scaled down to guard the thing that finds your things.
Why It Holds
CARBON-FILLED, NOT MOLDED
Printed in carbon-fiber-reinforced PA12 nylon. Geometries injection molding cannot reach, at stiffness-to-weight ratios silicone cases cannot dream of.
±0.1 MM OR IT SHIPS AGAIN
Every batch is dimension-checked against CAD. The watch drops in with zero play and the plates close on it like a mold — bolted, never clipped.
BRASS INSERTS, STEEL BOLTS
M3 torx screws seat in brass threaded inserts, not raw plastic. Open it a hundred times; the threads will not care. Tested from −30 °C to +80 °C.
ENGINEERED IN GERMANY
Designed, printed and packed in our Berlin facility. Shipped worldwide with recyclable, plastic-free packaging.
THE WORKSHOP — GERMANY
ABOUT — THE MAKER
Hi, I'm Filip.
Tinkerer. Maker.
No corporation — one workbench in Germany, ideas chased to the drawing board, and parcels shipped worldwide within 1–2 days. Feedback is always welcome.
MEET THE MAKER →Questions, Answered.
01 How fast do you ship?
Parcels are dispatched from Germany within 1–2 days of your order. Standard delivery takes 5–7 days, express 2–3 days — worldwide.
02 Do you ship worldwide?
Yes. Everything is designed and printed in Germany and shipped wherever you are. Shipping is free above €60.
03 What material are the cases printed from?
Carbon-fiber-reinforced PA12 nylon (PA12-CF): stiff, light and temperature-stable from −30 °C to +80 °C. Every batch is dimension-checked against CAD to ±0.1 mm.
04 Are the STL files really free?
Yes. The exact CAD we print from is downloadable on every product page under CC BY-NC 4.0, including the threaded-insert drawings. Print it, measure it, modify it — or order ours and know precisely what you bolted together.
05 Does a bolted case affect charging, signal or buttons?
No. The openings are designed in: the MP-01 charges on any Watch charger without disassembly, the AT-02 leaves the AirTag dome exposed for signal and speaker, and the CP-03 keeps the Epix display and side buttons fully reachable.
06 Is the paracord loop included?
Yes. An olive 4 mm paracord loop ships in the box with every case — thread it through the integrated lanyard slot, no adapter needed.
07 Can I return a case?
Yes — 30-day field-test returns and a 5-year structural warranty. And if a tolerance, a chamfer or a whole idea could be better, tell me: feedback is always welcome.
