iReed for Saxophone/Clarinet/Oboe customizer

thingiverse

This customizer creates a model of saxophone/clarinet reed (similar in construction). It develops ideas I put into the previous customizer (http://www.thingiverse.com/thing:1927038), and extends capability of the model to use wide range of curvature values of vamp crosscut for each element. Also each element is specified with its height percentage between tip base thickness (0%) and butt thickness (100%). Additional parameter specifies how much reed length is covered by vamp. The parameterized model of the customizer can be described as a cone section elements of different radius raised by tip thickness and its element rise that is intersected with the cylinder of reed blank. The reed blank is parameterized by: Reed Overall Length; Reed Cylinder Radius - defines curvature of the reed place in contact with ligature; Reed Butt Thickness - defines maximum thickness of ligature part of the reed; Reed Butt Width - defines ligature reed end desireable width; Reed Butt Width Stability - defines percent of contant width of reed from butt side calculated from overall length; Reed Side Curvature (Flat,Negative,Positive) - defines form of reed side not belonging to constant width part of reed specified by Reed Butt Width Stability: Flat specifies linear cut of side, Negative specifies concave form of each side, Positive specifies convex form of each side; Reed Tip Width - defines tip end width; Note that Reed Cylinder Radius and Reed Butt Thickness influence what is the maximum Reed Tip Width make sense, otherwise tip end exceeds rest part of the tip; Reed Tip Round - defines rounded form of the tip end - which part of Reed Overall Length is rounded with ellipse, or ellipse semiminor axis; Reed Tip Initial Thickness - defines tip end thickness. It is used as base thickness of vamp, which is added to all elements Reed Vamp Crosscut Rise; Reed Vamp Coverage (new) - defines percentage of vamp to Overall Length (default is 50%); Also each element specifies two parameters in this model: Reed Vamp Crosscut Rise Element N - defines percent of element edge rise between Reed Tip Initial Thickness (0%) and the level of Reed Butt Thickness (100%). Usually Element 0 has 0% rise; Reed Vamp Crosscut Curvature Element N - defines absolute value for radius of curvature for vamp crosscut at the element edge. Two neightbour elements curvatures define complex surface of the band that crosses vamp. That is it. Happy experiments with this reed engine. ;) Note that I did not test the reed model with default settings. Default settings just show flexibility of the new customizer engine in defining reed vamp surface. Updates: 05/14/2017 - added two parameters to the model: Reed Butt Width Stability Reed Side Curvature Both may be useful to create model of double reed for Oboe, English Horn, Bass Oboe, Bassoon, and many other, because they require special form of reed side. The double reed can be constructed from two printed reeds created with this customizer and either regular reed staple or modeled reed staple printed on 3D printer. Models I developped and tested with this customizer: Clarinet Bb: https://www.thingiverse.com/thing:2338906 Tenor Saxophone: https://www.thingiverse.com/thing:2552007 Alto Saxophone: https://www.thingiverse.com/thing:2478608 Soprano Saxophone: https://www.thingiverse.com/thing:2501672 Bariton Saxophone: https://www.thingiverse.com/thing:2873379 Print Settings Printer: JGAURORA Z - 605S Rafts: No Supports: No Resolution: Layer 0.04-0.1 mm Nozzle 0.4 mm Infill: 100% is must for the printed reed to work Notes: Usually I used ABS for the reeds experiments, but I think about PLA as well since ABS is softer than cane material used for natural (vs. synthetic) reeds. PETG is also successful replacement for ABS. How I Designed This I used OpenSCAD
