I made models of stadiums in the past, this kinda reminded me of ways to improve for next time. I had lot of issues with stadium posts that the shades sit on looking back I should have printed flat connected by rails. If it’s on rails posts could have been rolled out and glued on.

I modeled it this way because, I only need the face for testing.

Got the face flattened with Onshape, but it’s expensive.

The Unfold app did pretty good job as well but there are small gaps, those can be fixed with any vector app. I like this app because it’s more general purpose and cheap.

Next step is to 3dprint and check if alignment check out on a base.
