Heya - this is still a work in progress. I wanted an alternative to the huge BTT Octopus case from https://www.thingiverse.com/thing:4883809 and decided to remix the case from @InnovationWorkstation. Thanks for providing the step files! I also added mine.

I also added a little octopus from https://pixabay.com/vectors/silhouette-octopus-vector-graphic-3311636/

The cover is designed for a 60mm fan. You can use also the original 80mm cover without problems - but I rather wanted one with screws instead of magnets.
