Cooling test - Overhang test

***What***
A test to see how well your part cooler performs, mainly on overhangs.
Prints in less than one hour.
The print can be taken apart at each level when it is done.
Two versions, with and without text on overhang surface.

Or my remix of it: https://www.thingiverse.com/thing:3071469

***Why***
Analyse how well you cooler prints overhangs and if it cools evenly over 360°.
I made this to help me design and evaluate my Opticooler cooling solution for Wanhao Di3. (It's what I used for the print in the pictures).

***Print recommendations***
To compare with my pics (PLA) use 100% cooling at 0,2mm layer height and 30mm/sec overall (make sure other settings does not adjust).
Print with enough walls and top/bottom layers that everything prints solid.
Experiment with different layer heights, speeds and temps.
