niversal Skadis Hook that the Vallejo rack came with. I modified all the different versions of CabbitCastle's design to work with the universal hook. If you want the step file, go to the original post. As he did, I add the description for each:

37mm
- Fits Vallejo Airbrush Colors, 32ml

25mm
- Fits Vallejo dropper bottles, standing up
Blank
- For adapting to your own bottle sizes
- Available for 3, 4 and 5 pegs on the Skadis board
- Available STEP file format in the original post
Attachment Hooks
- Added the same Universal Hooks that are used on Vallejo Paint racks
