  • Q: What are the recommended print settings for STEMFIE?
  • A: I designed @Stemfie3D to 3D-print optimally, using standard print settings on filament-based 3D-printers, such as the following:
    • Material: PLA filament
    • Layer height: 0.2 mm
    • Perimeters (shells): 2
    • Top solid layer count: 4
    • Bottom solid layer count: 3
    • Infill: 15%
    • Generic print speed: 50 mm/s
  • Q: How many files, what types of part will be published, and when?
  • A: The STEMFIE project contains many parts which are currently 3D-modelled and soon will be ready for publishing. The construction kit has a vast ecosystem of components similar to traditional mechanical playsets. All parts will be gradually published here on, having the central file repository via – where users can browse all part and download them.
