free download 3d model Mechanical Counter

Update: I modified some parts for better printing and mechanical results, the modified parts end with “_V2”. if you don’t have a problem printing threaded parts, I recommend using the first version of “Main_shaft” and “Zeroing_knob”.

This is a fully 3D-printed mechanical counter designed to count up to 999. Made entirely from PLA with no metal springs, screws, or additional hardware. The design is optimized for easy assembly, making it a perfect project for both beginners and experienced makers.
