* More 3D printer friendly linktype (e.g. Try it out at or start with a slightly bigger example. * Possibility to restrict allowed angle of movement As for complexity, Ive been in projects where we had many millions of lines of code, integrated with over 100 systems, and 24/7/365 required uptime. If you have any questions, feel free to leave a comment. For example, the simple version of a door or a window could just be a square hole in the wall with indication for hinges, and the detailed held the full object. I will surely update it with a better structured and commented version sometime later. Please, don't mind the bad formatting of the source with German words in the comments, I just quickly made this in one afternoon, as I needed it as a quick and dirty solution for my 3D printer project, but I thought, maybe it could be of interest to somebody here, so I put it here anyway in this "beta" version. But maybe it could be of interest for you how to generate parametric chains, as OpenSCAD is a functional language you cannot use "for" loops and variables, for evaluating the input vector, it has to be made in a recursive function. I will add a link type optimized for printing. Openscad Animation Tutorial Coleman Biasi Book - Mighty Ape. If you want to print customized chain links, you can of course just set the chain length to a single element and export the. OpenSCAD - Intro and Example: Designing a filament holder. I made this to be able to quickly add cable chains in a solid geometry format into my FreeCAD Printer Assembly. The chain links are not optimized for printing. The vector:ĬhainDef = ,] ĭefines the example cable chain shown as screenshot.ĬhainDef = ,] ĭefines the version I use in my 3D printer for the xy-axis. There is a tupel consisting of the chain link type (at the moment there are only type 1: restricted to 45° movement and type 2: +-45° movement, type 3 generates a nice looking closed but mechanically not necessarily reasonable closed chain, type 4 onwards is just the same as type 3) and the angle of this link towards the previous. The Cable Chain is generated though a nested vector. In future the will be an additional option to differing link types, to restrict angular movement of the chain. Here you can specify a vector consisting of the angles towards the previous chain links. stl Surfaces.Īlso I wanted to be able to build not only a single Chainlink, but a complete cable chain. openscad if statement OpenScad beginners tutorial - EduTech Wiki. The Cable Chains I found here were mostly only. I was looking for a fully parametric cable chain, capable of output in CSG. As I did not find a cable chain suiting my needs, I decided to make my own.
