Air Spring

Airsprings represent a solution for 3D printing elastic elements. Unlike coil springs that are difficult to print and often brittle, airsprings use a pneumatic approach that combines the inherent flexibility of TPU with the compressibility of air trapped in the internal volume.The design is based on fully hollow cylinders with corrugated side walls that create an optimised 'zigzag' profile to facilitate controlled folding of the TPU. Advantages:More sturdy than 3D coil printed springsLonger lasting, without risks of warpingParametric Customization Customizable ParametersOpen the OpenSCAD project to customize:Height - Total spring dimensionsDiameters - Maximum and minimum wall expansionNumber of coils - Controls flexibility and compression rangeEnd height - Smooth mounting surfacesChamfer transitions - For optimal stress distribution This is v 1.0, if you have improvements please comment. The force of the springs repends on the air not escaping, so larger diameters may not suppo
