Hydralyte/Voost Lab Tube Rack - easy print/less filament

I remixed the original model to include a decorative triangle on both sides, and slicing a little bit of height off the top. 

This remix requires only 97g of filament, compared to the original which required 158g (both at 10% infill). It can be printed without supports (just lay the model on the side). 

My settings:

• 0.2 layer height
• 10% infill
• Marble PLA+
• NO supports 
• NO skirts/brims/rafts
