Introduction: Organic Geometry Lampshade
In this instructions the open source modeling software blender has been used to model the lampshade. The instruction outlines the blender workflow.
3D Modeling software (Blender 2.82)
Slicer programm (PrusaSlicer)
3D Printer (Prusa i3 MK3)
Filament (PLA Natural Transparent 1.75mm)
First draw a profile in edit mode and apply the screw modifier.
To subdevide once the subdevision surface modifier was used. The loopcut for beveling has been marked in edit mode to apply the bevel modifier.
Before you go further, make a copy of the lampshade mesh. Use the Tissue addon and apply dual mesh for the voronoi look to one of the two meshes. Then apply the wireframe and the subdevision surface modifier.
Use a lattice and the lattice modifier to strech the lampshade, if you like. Apply the lattice modifier also on the copied mesh.
Add a 2mm ring to make the lampshade stay in place.
Use the 3mf-file or the stl-file to print the mesh. For better printing split the lampshade into two parts. The one on the foto was printed with the Prusa i3 MK3 3D-printer.
