3D printed CPC mini: Tiny build, big Amstrad energy

There is something especially pleasing about seeing an Amstrad CPC recreated in miniature, and even more so when it is not just a display piece but a proper working build. Simon recently 3D printed the CPC Mini based on Archer’s Amstrad CPC464 Mini design, a functional mini recreation of the classic machine that uses the CPCESP emulator.

From the outside, it has all the charm you would hope for:

  • It is instantly recognisable as a CPC
  • It has that distinctive shape and keyboard-first design
  • It will still make Amstrad fans smile!

But, as ever with projects like this, the real story is in the build. One of the biggest jobs was the keyboard. Simon said it took a lot of detailed soldering to connect all the keyboard wires, which gives you a good idea of how much patience went into getting this little machine working properly. Mini builds have a way of making every task feel fiddlier, and this one was no exception.

Of course, no hands-on retro project is complete without at least one moment of mild chaos! In this case, Simon managed to put the S on the keyboard the wrong way up. Thankfully, it did not escape notice for long. His partner Jo, also a founding member of UKAG, an Amstrad Action writer and journalist, spotted it. So the build now has one of those brilliant little stories that every good project deserves: the kind where everything is nearly perfect, apart from one rebellious keycap trying to start its own alphabet.

That is part of what makes builds like this so enjoyable. They are not just about the finished object. They are about the process, the problem-solving, the tiny details, and the moments that make you laugh afterwards.

A project like this is a tribute not only to the original Amstrad CPC464, but also to the creativity and enthusiasm that still surround the machine today. The MakerWorld model itself is described as a tribute to the 1984 original, recreated in a compact but functional format.

Simon’s finished CPC Mini is exactly the sort of thing UKAG exists to celebrate: a mix of technical skill, retro affection and the occasional upside-down letter.

You can see the CPC mini, plus more that Simon has done on this project, at our meetup in June! The tickets are selling fast, and with projects like this on display, it’s no wonder!

Who is Simon “DOC” Green?

Christmas day December 1984, that’s when my lifelong love of the Amstrad CPC 464 started. The family had joined together and purchased me the Amstrad CPC 464 with colour monitor, and it included the free pack in 12 games.

Hi, my name is Simon, one of the founding members of UKAG.

We are getting the band back together, the Amstrad CPC Band. Yes the CPC may not have been as popular as the ZX Spectrum or the Commodore 64 in the school playgrounds across the UK, but there was a reasonably sized user base in the United Kingdom and across Europe, particularly France and Spain.

During my college years the CPC was my workhorse for courses, and for some weird reason I got hooked on writing database systems in basic. Then in the early 1990s the CPC scene was at it’s height: public domain libraries were the thing and I ended up running Penguin Software following the passing of its creator Davis Carter.

I was also getting into assembly language writing demo programs under my pseudo of DOC, and produced The Television Demo by Conspiracy. I had a few guest parts in other British coders demos, especially Wulf Demo III.

Fast forward to now, I still have my original 464, and over the last 10 years I have repaired and refurbished many Amstrad CPCs whilst completing the trilogy of CPC machines for my collection (464, 664 and the 6128). The 472 still eludes me, but one day…

More recently Chris Green brought back The Kickstart Amiga Group which met at a venue local to me. Slowly but surely at each of their events I have been spreading the word about the Amstrad CPC. This is where I met two of our other UKAG founders, Adam and Mac. Rob has always been around since the old school days. I met Nick (TechNick) through the Novabug YouTube channel and the lovely Jo is my life partner. We also go back to the WACCI fanzine days. 

After a year or so of meeting a couple of times in my kitchen to scratch the CPC itch we decided as a collective to put on an event, and with the amazing support of Chris Green and the Kickstart team, this is now happening on 21st June 2026.

This will be the first user group meet in the UK since the last WACCI convention somewhen in the 1990’s and the team can’t wait to see you all with your CPC’s for this amazing event.
