@dipstick ... I'd love to have a look at the file. Your Blender work has made me want to finally get to grips with it, and have spent a lot of time today playing and getting used to the controls. One question ... have you any idea when in either edge select or face select in Edit Mode, for some reason it doesn't capture the whole edge to be able to drag it with 'G' and 'X' keys to elongate it 🤔
Back onto Paint.net.
BarbieQ's Challenge ... tweaked the hex shell to not be so rounded (used this principle ) ... thanks Dipstick. Added the boxes
