General
In search for a mechanical counter to match with my engine models, I came across this beautiful prototype by 3D Printy: Mechanical Counter Prototype by 3D Printy | Download free STL model | Printables.com.

Printing and Assembly
For assembling instructions of the counter, I gladly refer to his excellent YouTube video:

I used the \u201cGLUE\u201d-option, no metal parts required.
Some parts were slightly modified, to assure a smooth running counter.
Also the counting order was reversed, as a consequence of the spur gear drive.

The counter is glued to the case on an angle. Take care of the gears to run smoothly.

I printed the model on a PRUSA MINI, with PLA+ filament, layer height 0.15 mm.
I use Hard Plastic Glue where necessary.

For assembled and exploded views, use .stl files 0\u2026 01... 02 (do not print).
Printing and assembly in alphabetical order (A1 \u2192 X1).

Dimensions (2 digit model): 111 x 55 x 108 mm.
Weight (2 digit model): 0.1 kg.

3 Digit Model
Use the parts in \u201cX1-Parts for 3-Digit Counter.stl\u201d to make a 3-digit model.
These parts replace \"B1-Case.stl\", \u201cB2-Case.stl\u201d, \u201cB4-Axle.stl\u201d and \u201cB9-Window.stl\u201d.

Matching Models
This counter can be matched with my engine models 4 Stroke Flathead V-Twin Engine by Bootjevaarder | Download free STL model | Printables.com and 4 Stroke Flathead Engine by Bootjevaarder | Download free STL model | Printables.com by glue-ing the \u201cD1-Adapter-Engine.stl\u201d to the crankcase sprocket of the engine and optionally using \u201cC2-Sled.stl\u201d.
A match can also be made with the gearbox model Constant Mesh Two Speed Gearbox by Bootjevaarder | Download free STL model | Printables.com with the \u201cD2-Adapter-Gearbox.stl\u201d.
