This ZIP file contains an assortment of commonly used STEMFIE parts in different sizes nestled into compact build plates measuring less than 140x140x140 mm (5 ½ inches squared), which fits comfortably in most 3D printers' build volume.

Start by importing each .3mf file into your 3D printer's slicing software. All components are oriented to 3D-print optimally without support structures. Please ensure a flat, clean build plate and calibrate it well.

If you use a filament-based 3D printer (FDM/FFF), I recommend PLA or PETG material for making STEMFIE parts. In addition, the following printing settings work well for making STEMFIE parts.

  • Material: PLA filament
  • Layer height: 0.2 mm
  • Perimeters (shells): 3
  • Top solid layer count: 4
  • Bottom solid layer count: 3
  • Infill: 15%
  • Generic print speed: 50 mm/s
  • No support structures

STEMFIE is a free and open-source educational toy! So have fun 3D-printing lots of parts and inventing your project builds!
