$fs : minimum circumferential length of each fragment. center false (default), z ranges from 0 to h true, z ranges from -h/2 to +h/2 $fa : minimum angle (in degrees) of each fragment. Parameters h : height of the cylinder or cone r : radius of cylinder. r1 & d1 define the base width, at, and r2 & d2 define the top width. Using r1 & r2 or d1 & d2 with either value of zero will make a cone shape, a non-zero non-equal value will produce a section of a cone (a Conical Frustum). The 2nd & 3rd positional parameters are r1 & r2, if r, d, d1 or d2 are used they must be named. If a parameter is named, all following parameters must also be named.Ĭylinder(h = height, r1 = BottomRadius, r2 = TopRadius, center = true/false) Parameter names are optional if given in the order shown here. When center is true, it is also centered vertically along the z axis. does not have as many small triangles on the poles of the sphereĬreates a cylinder or cone centered about the z axis. also creates a 2mm high resolution sphere but this one this creates a high resolution sphere with a 2mm radius $fa Fragment angle in degrees $fs Fragment size in mm $fn Resolution default values: sphere() yields: sphere($fn = 0, $fa = 12, $fs = 2, r = 1) For more information on these special variables look at: OpenSCAD_User_Manual/Other_Language_Features d Diameter. The resolution of the sphere is based on the size of the sphere and the $fa, $fs and $fn variables. center false (default), 1st (positive) octant, one corner at (0,0,0) true, cube is centered at (0,0,0) default values: cube() yields: cube(size =, center = false) Ĭreates a sphere at the origin of the coordinate system. Parameters: size single value, cube with all sides this length 3 value array, cube with dimensions x, y and z. Argument names are optional if given in the order shown here.Ĭube(size =, center = true/false) When center is true, the cube is centered on the origin.

4.3 Point repetitions in a polyhedron point listĬreates a cube in the first octant.

NOTE: This documentation is a work in progress, just like the rest of the repository, so parts may still be under construction. Their respective wiki pages go into more depth. These files are not meant to be exposed to the user, except for special requirements that the normal parameters cannot handle. The two files which do not follow these conventions are gridfinity-rebuilt-utility and gridfinity-rebuilt-constants.

Construction (Script-Specific Modules and Constants).

However, all modules are packed up nicely, so any module can be imported into other files or have more custom modifications beyond tweaking the parameters. Most files will come ready-to-run, so parameters can be changed using OpenSCAD's built-in customizer window, and the bins will automatically generate. It is not a requirement to use development versions of OpenSCAD.

This can speed up rendering from 10 minutes down to a couple of seconds, even for comically large bins. To enable the feature, go to Edit > Preferences > Features > fast-csg. As of writing, this feature is only implemented in the development snapshots. Getting Startedįor best results, use a version of OpenSCAD with the fast-csg feature. There are some fillets that are too small and too difficult to be worth implementing, as most printers do not have a high enough resolution for it to matter. This allows for internal fillets that nearly match the originals. First, the solid bin and bases are constructed, and then the compartments and holes are removed. This wiki aims to document these modules in great detail. The project has expanded into more eccentric models that use modules from the original generator. Thus, a pure mathematical approach using OpenSCAD can allow a single solution for all possible bin variants. Many major CAD suites struggle with making parametric models constructed from linear patterns, due to changing fillet edges and seams. Gridfinity rebuilt aims to remake the brilliant Gridfinity project from Zack Freedman in a more robust and open-source way than the original Fusion 360 files.
