FIG 1.0 — MP-01 / APPLE WATCH ULTRA
MP-01 Ultra Case
The smallest phone you own. Your Apple Watch Ultra, off the wrist and bolted into a pocketable handheld — calls, maps, music, payments. No feed.

Everything You Need.
Nothing That Feeds.
A cellular Ultra already does the useful part of your phone. The MP-01 gives it a body built for the pocket instead of the wrist: the display sits flush behind a machined frame, the digital crown and action button stay free, speaker and microphone stay open. Text back, take the call, pay at the counter — then put it away, because there is nothing to scroll.
It weighs 54 grams. It hangs off a pack zipper by the paracord loop through its lanyard slot. It has never shown anyone an ad.

ASSEMBLY — 3 LAYERS, 6 BOLTS

Bolted,
Never Clipped.
Two carbon-fiber-nylon plates close on the watch like a mold and bolt together with six M3 torx screws seated in brass threaded inserts — Ø3.6 mm blind holes, torqued to spec, reopenable a hundred times without wear. No snap-fits that fatigue, no silicone that stretches, no chance of walking out of a pocket in pieces.
The back plate opens over the sensor dome: drop it on any Watch charger without touching a bolt.

CONFIGURE MP-01Questions, 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.
