This is my fully functional (FF) 3x3x5. I used CBCubes’s tutorial which I prefer over redKB’s tutorial because it’s much easier to build and the result is much nicer. I know this because I have built a 3x3x5 using redKB’s tutorial and it was much harder than this version. This cube took me roughly 3 hours to build and it turned out very good. I hope you enjoy!
