Original concept https://twitter.com/peter6409/status/1207609072528183296 by Peter6409 over Twitter (https://twitter.com/peter6409). I liked the design so I decided to make it in 3D.
This is a personal project, just for fun and practice. I wanted to practice clean modelling and shading, especially on curved surfaces, without using Booleans. I'm quite happy with the result.
For texturing, I used Grungit ( https://www.artstation.com/marketplace/p/j0mD/grungit-for-blender ) and I adjusted the node a little bit.
