You sir, are a genius, everything looks incredibly simple yet perfectly suited, your flavour "racks" make me think spice racks would work really well, you could wall mount them over your mixing bench.
At the moment I have a cardboard box with a partition, flavours on one side and 10ml / 30ml bottles and syringes on the other.
"Pick up, no, pick up no" - I'm feeling that one lol
This is definitely food for thought and I have a few projects in mind for organising my vape gear, tanks, mods and accessories etc so this helps me tons.
Thanks for sharing, happy vaping!
