Before you join

Fair questions.

  • Isn't it too saturated already?

    For dragons and fidget toys, yes. Everyone's printing the same free files and undercutting each other. That's not where our money comes from. Ours comes from replacement parts you can't buy any more, batches for businesses, and our own products. That's where we'll point you.

  • Is there actually money in it once you count your time?

    Not if you price by the gram. At the start we sliced the file, added 70% and undercharged by about one to two grand. Now we price in the machine time, the wear, the failed prints and our hours. We'll show you exactly how.

  • What's the catch with free?

    No webinar that turns into a coaching pitch. The free side is everything explained: every guide, the tools and the community. You do all of it yourself. If you later want us to do some of the work for you, there are paid tiers from £29.99 a month. You never have to.

Who's behind it

James and Freddy. We started with one printer in James's room at uni. In year one our business invoiced £87,274, and we've had more than 130 paying clients since.

That's what it did for us. What it does for you depends on what you print and the hours you put in.
