Behind the scenes · Actual photographs
Before a generator becomes useful, we have to see what comes off the printer. Here are a few unpolished moments from our own production and experiments.

Every new customer brings a different logo, name or link. These are five products we actually printed — and the real customization problems that inspired our product generators.

B2B ORDER · REPEAT CUSTOMER
Custom-branded keychains
Our first independent paid bar order was 50 oval keychains. The original design needed manual and AI-assisted refinement; now you can customize its production format in a generator.
The shape stays the same. The business logo, colours and text can change for the next order.

CAFÉ · 50-TAG PILOT
Branded NFC & QR touchpoints
We tested 50 branded NFC tags and QR links to help café visitors reach Kiska's review page.
The next café needs its own branding and review-page link, not a new product from scratch.

DEMONSTRATION PROTOTYPE
A company-logo keychain
A physical prototype explores turning company artwork into a branded tag for NFC-based contact sharing.
A different customer can supply a different logo and contact destination for the same basic format.

OUR PRODUCT · PET ID
Personalised pet identification
The Bella tag shows how a pet's name and a scannable link to an editable online profile can become a useful physical product.
Every pet gets a different name and profile link while the printable tag format remains reusable.

LOCAL SERVICE BUSINESS
Business-name & phone tags
Round black-and-yellow keychains put the cleaning company's logo, business name and phone number in one small branded item.
The same format works with another business name, logo and contact number.
Master Tool Box 3D is turning these repeatable personalization steps into generators, so a new logo, name or destination link does not mean redesigning a product from scratch.
