Citadel Plug Modification

thingiverse

Hello everyone, that's my take on Citadel paints. My issue is getting color onto my palette. Vallejo miniature colors already have their own special plug. I tried to come up with this solution. I've never 3D printed before, maybe I made some errors. Please feel free to share and mix in your own ideas. If you print it out I'd appreciate any review - positive or negative - no problem. I just want to know what mistakes I might have made eventually.
