The vacation period has started and our response time will therefore be longer than usual between July 8th and August 15th. We appreciate your patience.

Modular Castle Playset (3D-printable)


We designed The Modular 3D-printable Castle Playset as a concept to demonstrate the potential of using 3D printers for home-based toy-making.

As the pace of hardware development increases, the traditional ways in which products are consumed can be affected by a rapid adoption of maker tools, such as 3D modeling software, 3D printers, and laser cutters.

During the past 20 years, the expansion of computing devices, digital cameras, and the Internet, created an infrastructure where individuals ubiquitously use digital tools. It has never been so easy for anyone to publicize text, images, and videos - directly from the comfort of one's home.

Today, the same seems to be happening with the adoption of design software and manufacturing hardware. This democratization can drastically change the way in which we invent, distribute and manufacture products.

Individuals will potentially be able to create and produce the products they need and desire. Modern digital tools, Creative Commons licensing, and the Internet as a distribution platform can create a new production era, which is parallel to the currently established methods. 

This #3DCastlePlayset aims to demonstrate that a fun toy can be defined, designed, distributed and adapted by individuals, using 3D tools and the Internet.


The structural parts of the castle (walls, towers, etc) are modular and fit together via a standardized butterfly-joint.

Download the files

You can download files free of charge from the following 3D printing file repositories.

3D-print settings

We recommend using PLA filament for its ease-of-use and being the most suitable plastic for 3D printing toys. 

  • Layer thickness: 0.2 mm (200 microns)
  • Perimeters (shells): 2
  • Infill: 10%
  • Top solid layers: 4
  • Bottom solid layers: 3
  • Print speed: 40 mm/s

3D printers

You can use any 3D-printer that is compatible for use with PLA filament. 



Note! Contains small parts. Only allow small children to play with the parts of the #3DCastlePlayset, during adult supervision.
