Mechanical counter made from plywood

This one is a nice demonstration how to give Plywood designs ability to move and show somesthing interesting. It also shows the abilities of pylaser lib from PythonSCAD. (pythonscad.org) The Counter is based on https://www.thingiverse.com/thing:4644252 , but this derivate is almost completely done from wood. Prerequesites: Lasercutter Paper printer 3mm Plywood 2 M4x50 screws 5 6mm Rivets Prepareation: In order to build it , please create lasercut 1x counter1.svg lasercut 3x counter2.svg. paperprint 1x labels.svg You get the svg files, by downloading the complete design as a zip file and browsing into the "images" directory Building: Carfefully sand the plywood pieces Assemble the case from counter1.svg like it looks like in the picture Assemble 3 big gears from 5 pieces each. use a central axle during gluing for good alignment and make sure there is good rotation alignment between all the gears Assemble 2 small gears from 3 pieces and take care about good alignment let the glue cure. Optionally: drill a 6mm hole into the gears, insert a rivet and drill a 4mm hole into the rivet. This will greatly improve reliability fo the counter as it prevents them from tilting. Glue the paper stripes onto the 3 big gears. Align them so they are readable like in the photo and "4" is located at the single teeth of the gear Finally assemble gears like in the picture. The small gears share 2 layer with the righthand gear and one layer with the lefthand gear Happy counting
