With AI. With 3D printers. And turning both into a real business. Three books, written and designed by an 11-year-old who actually did it — no fluff, no fake stories.

Write, publish, and promote your book with artificial intelligence. The complete guide — from a blank page to a published book on Gumroad and Amazon, in weeks instead of years.

Everything about printers, filaments, and techniques — from your very first print to work you'd be proud to sell. The reference book to keep next to your printer.

From your first paid print to a real business — Etsy, digital files, local B2B, and print farms. Including the chapter nobody else writes: what I actually sold, honestly.
From writing your first book with AI, to mastering the printer, to making real money with it. Three books, one story — the complete builder's path.
Real pages from the books — each one designed like it means it, because it does.



The first editions were plain pages of text. The all-new 2nd editions were redesigned from scratch — every cover, every chapter, every table. Same honest content, finally dressed for it.
I'm Peter. I'm 11, I go to Herder Gymnasium in Berlin, and I make things — books, 3D prints, games, websites. This whole series exists because my dad made a book with AI, I decided I could do it better, and then I did it three times.
Everything in these books is real. The workflows are the ones I actually used. The 3D printing advice comes from real prints (and real failures). And the business book ends with exactly what I've sold — dragons and whistles to kids at school — because honest numbers beat big promises.
I also wrote Raise a Builder with my dad — a book for parents about raising kids who make things.
Instant PDF downloads, readable on any device — phone, tablet, computer, or printed out. No apps, no accounts, no DRM.
Pay what you want, from €1. I'd rather a thousand people read them than a few. If a book helps you, you can always pay more — some people do, and it's awesome.
No. Each book stands alone. But they do tell one story — write with AI (1), master the printer (2), make money with it (3) — so the order is there if you want the full path.
Yes — with AI as the assistant, and me directing, editing, and deciding everything. That's literally the method Book 1 teaches. The books are the proof it works.
The books cover the questions I hear the most. If you're stuck on something, the communities listed in the resources sections are genuinely helpful and fast.
