I was looking for scalable, stackable trays to be printed in Vase mode.

Unfortunately I couldn't find any, so I decided that I need to design my own.

I created two sizes (dimensions of main compartment):

• 60x40x20mm
• 60x60x20mm

If you just need bigger / smaller tray then you should be able to just scale them directly in slicer.

I printed mine with settings:

• Filament: Marble PLA (Layer time goal set to 9 seconds)
• Layer Height: 0.3mm
• Layer Width: 0.72mm
• Solid bottom layers: 3

Printing time on above:

• 60x40x20mm - 14 minutes, 5.61g of filament
• 60x60x20mm - 16 minutes, 7.36g of filament

If you need tray in different dimensions or shape - just let me know.
