About this 3D model

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 “GLUE”-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… 01... 02 (do not print). Printing and assembly in alphabetical order (A1 → 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 “ X1-Parts for 3-Digit Counter.stl ” to make a 3-digit model. These parts replace " B1-Case.stl ", “ B2-Case.stl ”, “ B4-Axle.stl ” and “ B9-Window.stl ”.
