NOTE: New XL Size Added! We’ve increased the width to 300 mm for the trays and back bar—perfect for those who need a bit more storage space

Here is another airbrush paint holder! I designed this version with trays to eliminate wasted space and maximize storage capacity. 

It features five trays in total: four are 31mm wide to fit a variety of small bottles, 

while the bottom tray is 38mm wide for larger ones.

The entire rack is designed to be assembled without glue. 

I’ve included a back bar that uses simple wedges to secure everything,

but I've also provided a standard back bar if you prefer to use glue. 

Finally, I optimized the design to be as filament-efficient as possible!

Key Features:

• Optimized Storage: Includes 5 trays. Four are 31mm wide (perfect for standard dropper bottles) and the bottom tray is 38mm wide for larger bottles.
• Tool-less Assembly: Designed for a snug fit without the need for glue.
• Versatile Back Bar: Features a wedge-locking system for a mechanical hold, though a glue-on version is included for those who prefer it.
• Lightweight Design: Optimized to save filament without sacrificing strength.
