The original file that I remixed is this, I have added new features to test.

I added new things to test like stringing test and the write on the bottom. You can also test a lot of other things:

• bridging
• bed level
• stringing
• calibration test
• overhang performance
• cooling performance
• general small feature

Reminder: before printing you have to go to:

“Print settings” → "Layers and perimeters" → Enable "detect thin walls".

Please leave a comment for any question!
