Customized version of http://www.thingiverse.com/thing:53235 Created with Customizer! http://www.thingiverse.com/apps/customizer/run?thing_id=53235 Instructions Using the following options: Gear angle at midpoint is -5. The base frequency in C0 is 16.3516 Hertz. Tooth width for gear to hub is 1.875 inches. The pulley height above platform is 10 units high. For printing purposes, there are mid size teeth equaling 8 each. Small radius on crank axle is exactly 3 mm round. The crank shaft has a tooth count of 8 units wide. Snap on linkage length is 1.2 mm long. GENERATE_MID_GEAR option is enabled and set to value "X". GENERATE_CRANK option is enabled and equals "X" also. The pulley slack value is equal to zero-point four mm thick. Tolerance level for gear machining operations will be 0 point one inches precise. A Music cylinder label with specified name will be generated in case option set is on music type device input name given here. Value equals 0 point six, or twenty millimeters tall. Wall thickness set by operator or default settings to two millimeters strong. Set the gear clearance space distance from center shaft line axis between gears of approximately 1 inch wide and minimum zero-point-one (min) thick. Enable "epsilonCSG" variable setting equal zero-point one. GENERATE_CASE option enabled which represents "Yes". Enable GENERATE_MUSIC_CYLINDER with given values already provided on other input forms. Crude or refined tooth cutting tool holder height for gear production operations must match value here stated at exactly 5 mm vertical space gap from platform floor plane surface. Axis holder slack clearance between main rotating axis parts to ensure good print job finish set in parameter named axisSlack and having zero-point three inches loose. The density E for given PLA type filaments comes out being approximately 8.24 million units volume/weight. Size in point seven of letters that represent note names used here written as Music CylinderNameFont write/Letters.dxf file format saved earlier or loaded currently on host system computer now ready to execute printing task operations. Music cylinder axis holder height calculated from geometry information previously given and measured equals three point four (3.4) inches tall. A value of 35 is set for the y-direction pin array count. Number X pin array positions equals 13 horizontally across. A crank gear rotation angle that defines orientation has zero position at time t =0 sec or start and defined by number crankDirection variable equals zero. A total pitch diameter value in Hertz (frequency unit) given for this machine tool used in all cutting tasks related hereafter named "pitch". Its measurement value recorded now was equal exactly to diametral_pitch = 6 / 10. Values that match parameter pinH input name equals pin height calculated result one five (1.5). This must match specified output generated by operator elsewhere for final desired product result print. An output file will contain a set number called F note names written inside the gear, each with specific size (diam) depending upon given user settings for "music axis" options - i.e. these are C#-notes only - listed vertically at regular distances from origin along cylinder center axis of specified MusicCylinderNameFont write/Letters.dxf file saved previously as input file named musicAxisHolderH measured equaling exactly 3 point four inches. Values match other known calculated variable quantities already assigned to the parameters noted for generation by code name and parameter alias midBigTeeth now recorded or used for this example task. Value given value one hundred percent of actual units desired measurement set up equals total of two dozens as written number twenty for crank teeth quantity or total teeth count present on rotating crank axis shaft here defined - which is equivalent mathematically in expression of formula f(x) = n * x as thirty-two. An option has been generated that allows one to create multiple snap locations at a variety specified angle value from main snapAxis point via this named snapaxis parameter name. In output file F# notes and all related variables defining them should have diameter D equivalent or larger since music gear must hold full C note frequency (hence always above half C at mid range point 6). So value "wall" should be made equal or greater in height as one.
