I wanted a simple and quick to print but still useful test to fine-tune a multitude of parameters, so i made this. This is not a test to test the limits for your printer, but rather finding a "good enough".

These are some of the things i can test with it:

• Dimensions: The basic cube is 20mm, the holes are 10mm and the well on top is 16x16mm on the inside with 2mm thick walls.
• Layer adhesion: Use pliers to break the upper wall off or put the pliers in the round hole trying to pry the block apart.
• Stringing: If stringing is a problem you will see it in the holes and/or the well.
• Ringing: Could be seen around the holes, corners, or dimples around the well.
• Surface smoothness: Both walls and top layers are visible.
• Loose belts: Look for weird artifacts around the rounded corners.
• Overhangs: The overhang on the outside is easy, the round hole might be a bit harder but not insane.

• Bridging: Mainly tested by the square hole. Let me know what more you can test with this little print.
