PetriStack - The Expandable & Scalable Petri Dish Rack

This model is designed to work with ~70mm petri dishes. 

I am using it for agar plates for mycology work.

Thanks to it's very simple design it can be scaled to any size needed for bigger or smaller petri dishes.

The dovetail clip allows you to attach them together infinitely. Print two of these per connection with your regular infill and wall settings. I use 3 walls and 15% gyroid.

If you print the main body with two walls and 15% lightning infill, the print is only ~170 grams of plastic, which costs me approximately $2.50 AUD. So it is a quick and cheap way of storing/stacking petri dishes for biology work.
