Description
An open-source wall-mounted shelf generator for openGrid, utilizing the openConnect system. It is called the "Sturdy Shelf" because it is designed to be printed on its side. This circumvents the most common weak point of 3D prints—layer line separation—ensuring maximum structural strength for the shelf.
Customization: You can adjust the width, depth, and thickness of the shelf, as well as the raised edges, truss length, and strut spacing. You can use the MakerWorld Customizer or download the source file to use with OpenSCAD and the BOSL2 library on your PC.
Surface Texture: Surface texture is enabled by default to hide layer lines and other 3D printing artifacts. While the texture looks rough in the preview, the printed surface actually feels quite smooth to the touch. This can be turned off in the Customizer, and the texture depth and size can also be customized.
Combining Parts: By enabling connector holes, you can print shelf segments separately and join them into a single wide shelf. The connectors used are the same as those for openGrid boards. I have uploaded a .3mf file as a demonstration.
Slim Version: If you prefer a simpler design, choose "slim" in the shelf_type settings. This version is lightweight, filament-efficient, and only occupies one vertical grid space.
The model is open-source under the CC-BY-SA license. Like all the OpenSCAD models I've designed for openGrid, it can be found in this GitHub repository. Feel free to use the code; feedback and suggestions are welcome.
Also, if anyone is willing to do a detailed test of this shelf's weight-bearing capabilities, I would really appreciate that!
