My approach for cartoon design of the Gary Goodspeed helmet as seen in the Final Space Series for your Cosplay. Is not official design or similar.

Due to the big head size and to be near proportion I had to decline the helmet base to avoid to hit shoulders if you want to wear it.

• STL file provided (created and validated with meshmixer)
• Check your head measures before printing and scale it to your size. File not divided. You have to divide it to print in parts to suite your printer
• I welcome any suggestion to revamp the model
