Gap Test (Snail)
1. This snail is an STL file used to test the printing gap accuracy, the gap distance in the model includes
     0.12mm/0.15mm /0.2mm/0.25mm/0.3mm/0.35mm

2. As long as the 0.2mm circle can rotate, it means the accuracy is fine.

3. There are many factors that affect printing accuracy
     A. Filament diameter error or inconsistent thickness.
     B. Machine tuning problems, nozzle wear or uneven platform...
     C. Slicing settings are incorrect.
     You can increase the gap by shrinking the boundary, refer to the following link for gap adjustment

4. Regardless of whether the circle of the snail can rotate or not, it can still be used as a keychain, don't waste the material.
