Overhang Angle Stress Test

Just realised that i never done any overhang / angle stress test before... therefore rather to download one from the internet... I decided to design one by myself...

This testing tools consists of 6 different overhang angles: 15', 30', 50', 60', 70' and 80'... with a 50mm long bridging... I had tried 4 different PLA colours with 6 attempts... finally got 1 successful print...

Surprisingly the 80' are barely survive during the prints... I guess i need to adjust the design to 75' instead.... so let's try again...
