This two-digit counter has a stylish design! It has a wheel with a satisfying click sound. Each number stops with a click, and it's easy to assemble.

Assembly:

0. Print a total of 5 parts: 'Case_M', 'Case_F', 'Spring', 'Wheel_A', and 'Wheel_B'. Select a standard or reverse case, and choose either a normal or soft spring for the spring.

1. Install the wheels on 'case_M' and check their rotation. If they feel stiff, use sandpaper or apply a small amount of lubricating oil to the inside of the wheels.

2. Install the spring on 'case_M'.

3. Fasten the clips on the other side of the chassis.

Note:

• Suggested layer height: 0.15 - 0.20mmIn my slicer, if the layer height exceeds 0.28mm, the clearance between the spring and the wheels will disappear, and it won't work properly.
• Don't use matte PLA or silk PLA, as they have weaker layer adhesion and may break when clipped.
