Imperial credit (with sloping walls)

A version of the imperial credit, but with a small angle of inclination of all walls, which can be useful for metal castings (sand castings using them are quite difficult to make). It's also useful as a cosplay accessory or whatever.

I provide 2 print profiles, with the difference that one has smooth surfaces using ironing.

There are quite many verions of these credits, but this one is based on a one model i once found on Thingiverse. Unfortunetly I counld't find it anymore, because it was about a year ago (I checked everything I could find, but nothing resembled what I remembered.). It had quite a few imperfections, so with addiction of sloping walls I made, the changes are quite significant.
