3D Printed Pineapple Light

3D printing light covers and lamps are always fun projects, you can’t really go wrong.

Continuing from a previous post where I outlined the process of designing sea urchin light covers for my house, I’ve still been wanting to design another light cover to mix things up so each room isn’t the same. Enter the pineapple light!

Unlike the previous process of designing the sea urchin light from scratch using a 3D scan, this time I was able to find something on Thingiverse that was almost perfect – this model of a pineapple. The bottom part had a really nice geometric pattern that saved me hours of mucking around in CAD and designing the same thing from scratch. This is one of the things I love about the 3D printing community – the open sharing of 3D models to be remixed (also known as a mashup) just like a song or video into something new and creative. You can read more about remixing in one of my previous tutorials.

Similar to the sea urchin light, all the pineapple needed was to be scaled to the right size, hollowed, given a thickness, and have a neck piece added to connect with the light fitting. This neck piece was directly imported from my previous project in Meshmixer (free CAD software), and both pieces were joined together. Nice and easy!

Just like the sea urchin light, these pineapples were 3D printed on a Prusa i3 MK3S in a natural PLA from eSun – it’s a translucent material which I found from previous experiments to work really well for light covers when given a very light dusting of white spray paint. The painted exterior still allows the light to shine through nicely, but just helps define the form better than the natural finish on its own. If you want to see exactly how this compares to the natural filament on its own, or a pure white PLA, check out my sea urchin light post. This design can also be 3D printed without any support material.

Best of all, you can download my pineapple light cover completely free from Thingiverse, Pinshape, Cults and MyMiniFactory! Just like the original design of the pineapple which helped me in this project, I hope this remix will help you in your own project – even if you don’t have the same size light fitting as me, with a bit of editing in Meshmixer or another CAD program, you can easily modify this design to suit your own needs. Enjoy.
