I decided to design All In One 3D Printer test 2.0, so here it is. This test includes : support test, scale test, overhang test, hole test, diameter test and bridging test. Print this with 100% Infill without supports.

!NOTE! : If you are using Cura and you are experiencing missing text issue, be sure to enable "use thin wall" setting! (big thanks to CoreyNach for this!)
