Printed cases · a vertical run by Roman
It came off a Creality K1C on 2026-08-01 in 30 minutes 41 seconds, using 29.27 grams of black flexible filament. Roman is the engineer, the developer and the owner of this vertical. This page is the workbench it gets built on, in public, from the first unit.
One case. Printed once. Not for sale, and no orders can be placed. Nobody has confirmed yet whether it fits the phone it was made for, and the page does not know which phone that is. The configurator below builds a specification, not a quote.
Everything on this page that is a measurement came from the printer's own job record. Everything that is not yet known is marked as not yet known, including things you would expect a shop to have decided already. The list of those is further down and it is long on purpose.
This is the model the slicer actually sent to the machine, drawn by the slicer itself. It is not a product photograph and there is no product photograph yet, because the printed object has not been shot. Note what is not in the picture: no camera opening on the back face.
These numbers are read out of the machine's job history and its gcode header, not from anybody's memory. The job completed without error.
| Quantity | Value | Where it came from |
|---|---|---|
| Print time | 30 min 41 s | job record, print_duration 1841 s |
| Material used | 29.27 g | slicer estimate in the job file |
| Filament | TPU, black | job metadata, colour 000000 |
| Machine | Creality K1C | the flexible-filament machine of the three |
| Nozzle temperature | 205 C | gcode header, first layer |
| Bed / chamber | 60 C / 35 C | gcode header |
| Layers | 14 at 0.75 mm | gcode header, total layer number |
| Object height | 10.3 mm | the height of the case wall, lying flat |
| Revision | rev3 | the filename. rev1 and rev2 are undocumented |
A 0.75 mm layer is unusually thick for a phone case and it goes with the wide nozzle recorded on this job. That is a deliberate house style on these machines (one thick bead, drawn fast) rather than a mistake, but it has a cost in surface finish that nobody has judged against the alternative yet.
This is a proposal for Roman to accept, change or throw out. It is written down so there is something concrete to argue with, not because it has been decided.
| Choice | Draft position | Status |
|---|---|---|
| Material | Flexible TPU, the grip that a hard case does not have | printed once |
| Colour | Black to start, because black is what is loaded | printed once |
| Phone models | One model first, done properly, then widen | model unknown |
| Personalisation | A name or initials raised on the back | never tried |
| Texture | A printed grip pattern instead of a smooth back | never tried |
| Camera opening | Required, and the current model appears not to have one | needs Roman |
| Price | Not proposed. Roman sets it | needs Roman |
| Turnaround | Half an hour of machine time per case, plus the queue | measured once |
Pick a specification. The panel underneath tells you which parts of it have been printed and measured, and which parts nobody has made yet. It deliberately refuses to invent a price or a print time for a combination that has never run.
These are the questions blocking the next step. They are public because a stranger reading this page deserves to see exactly how far along it is, and because most of them are the same questions anyone starting this would hit.
Which phone is the printed case actually for?
The filename says iphone and nothing more. Without the model there is no product, only an object.
Where did the model come from: Roman's own design, a remix of someone else's, or a straight download?
The filename carries a name that is not ours. This decides what this page is allowed to claim and who gets credited, so it gets answered before any claim is made.
What changed between rev1, rev2 and rev3?
Three revisions means two things were wrong. Those two things are the most valuable knowledge in the project and they are currently only in Roman's head.
Is the missing camera opening deliberate?
The slicer preview shows an unbroken back. If that is an oversight it is the next revision. If it is deliberate, the reason is worth writing down.
How does it actually fit: too tight, too loose, or right? Does it come off without a fight?
TPU stretches, so a case can go on and then be a problem to remove. Only the person holding it knows.
What should the first real offering be, and what should it cost?
Owner's call. The material in one case is a few grams, so the price is about what it is worth to the person holding it, not what it costs to make.
This desk does not send anything. There is no Send button any more. Answer whatever you feel like answering, press Copy, and the answers land on your clipboard and in a box at the bottom you can read and select. Then give them to Oleg yourself, by pasting them into a message or just reading them out. Nothing you type here leaves this page on its own, and nothing you type here is stored on the site or published.
Where the answers go, honestly. Nowhere, until Roman hands them over himself. Until 2026-08-04 this desk posted what was typed to a notification service run by somebody else, and that has been removed: what a person writes now goes to their own clipboard first and travels no further without them. The page has no server behind it and stores nothing. There is still no way for a reader to send anything back to Roman through this page, by design.
