Gap test-fish

1. This is an STL file for testing the accuracy of the gaps, containing 4 kinds of movable structures that are often used in my designs.

2. Try printing this file before printing my other works to adjust the gcode settings. Once you confirm that all 4 parts can rotate, print my other works with the same settings to increase the printing success rate.

3. Try controlling the gap of movable parts by adjusting the flow rate.

4. If the flow rate drops below 90 and the result still fails, it may be due to the printer's adjustment problem.

5. Whether it can be turned or not, it can be used as a key ring, so do not waste materials.
