A fully mechanical, split-flap counter with a reset mechanism.
No electronics – pure mechanics.
Designed for smooth operation and reliable counting.

Perfect for:

• Counting repetitions or tasks  
•  Workshop / garage use  
• Events or games 
• Daily tracking without electronic
• Desk gadget for mechanical enthusiasts

Mechanism overview:

Each actuation advances the internal mechanism by one step.
The reset function disengages the counting mechanism and returns all panels to zero.
The design ensures consistent positioning and repeatable results.

Parts Needed

• M3 × 6 mm screw
• M3 × 5 × 4 mm threaded insert
