As featured on Pinshape’s ‘Pick of the Week‘
You may have already seen, or even downloaded, my Lightbulb Lampshade which I created a while ago to give a new lease of life to an old Ikea lamp. Now I’ve create a new version to fit the competition criteria of the latest Pinshape Design Competition for a low-poly design. Of course this means you can also download the file for yourself completely free, just click here to download from Pinshape, or here for Thingiverse 🙂
The model was printed on an Up! Plus 2 3D printer, using the 0.2mm layer thickness and minimal support material. As you can see in the image to the left, there really was only a small amount of support material generated in the middle to support the top section, and this broke away very easily. You can also see a small break near the bottom where the printer must’ve bumped the model as it was printing, but thankfully it kept printing. Overall it took about 4 hours to print. If you’re planning on making one, the minimum diameter inside the design to fit over your light fixture and light-bulb is 31mm – if you need it larger, just scale up the design before printing.
Above you can see the process of creating the 3D CAD model, this time challenging myself to use Rhino for the complete development rather than my usual Solidworks. This was to create the more complex form in a shorter amount of time. From left to right the process was:
- Use Revolve to create the light-bulb form.
- Convert this to a Mesh.
- Reduce Mesh to create the faceted effect.
- Use the Line tool to connect the points of the faceted mesh.
- Use the Pipe tool to add thickness to the lines.
- Add some solid sections to fill in some of the gaps, then Join all the pieces into a single mesh ready to export to STL.
If you make one please share your photos back on Pinshape or Thingiverse so I can check it out!
