"It took about 2 hours to model the "Steeler's Visor" (compressed to 15 minutes here).

Unfortunately I lost the recording of the belt so the video is not complete.

As a reference I only had the original "Dealer's Visor" item by Valve.

0:05 Started with the cap shape
2:15 Adding rivets
2:30 Modeling the upper part
4:45 Connecting the pieces
7:25 Adding belt
11:52 Adding more rivets
