Hi - I am new to 3D modeling, so any advice is sincerely appreciated. The measurements for the badge area are 53mm x 85mm, which is the size of a standard badge.
I based this off of a photo of one of the actual badge holders; I could not find the STL for this online, with the exception of one Etsy seller who was selling the badge holders for $30!
The author marked this model as their own original creation.
