What this video covers

Part 3 of SKS Props' Warhammer 40K Cadian armor build series focuses on constructing the iconic Imperial Guard helmet from EVA foam. The creator provides free downloadable PDF templates on his website, designed to scale correctly across multiple paper sizes when printed via Adobe Acrobat's poster setting. The video is part of a larger group cosplay project aimed at Dragon Con, with future installments planned to cover painting and weapons.

Key takeaways

  • Free PDF helmet and armor templates are available on the SKS Props website, printable at home using Adobe Acrobat's poster mode
  • The helmet is built from EVA/HD-Foam using standard cosplay fabrication tools including a heat gun, utility knives, and contact cement
  • This is Part 3 in a full Cadian armor series — additional videos will cover painting and possibly prop weapons
  • STL files for 3D-printed Cadian accessories (helmet, shoulders, rifle, etc.) are also linked for those who prefer that route
  • The project is beginner-accessible, though a full product and materials list points toward a more complete intermediate build
