Print Your Own Headset¶

Find the files on Github, and a quick tutorial on YouTube of V1.0 made by Nikolai Schauer. Please read the printing guide before trying to print.

Parts¶

Per headset, 3 pieces need to be printed:

  • 1x Main-Part.stl
  • 2x Attachment.stl

We recommend semi-flexible filament, but anything flexible should work. Stiff material like PLA, PETG or ABS won’t work! We used “Renkforce Flexible Filament” for all prototypes.

Print settings¶

We recommend these print settings:

  • Nozzle: 0.4 mm
  • Extrusionwidth: 0.5mm
  • Layerheight: 0.25mm Brim: 3mm
  • Speed: 20mm/s
  • Infill: 40% (This value can be adjusted to compensate for more flexible filament; a higher infill value will make for a more stiff headset)
  • Perimeters: 5
  • Bottom layers: 5
  • Top layers: 5
  • Temperature: See filament spool

The print settings are of course dependent on your personal printer and will most likely require some tuning. The parts were designed to fit on most buildplates, in some cases “Main-Part.stl” needs to be rotated by a few degrees (Prusa MK3 for example).
