Easy Print Voronoi Tealight Candle Holder

Summary Note: This project was not intended to be used with a real tealight - plastic and fire does not mix well so I strongly recommend you go and get an LED tealight with a flickering effect. They are super cheap to buy. 

I have been meaning to have a go at my own Voronoi style tea light holder for some time. I am pretty happy with it! And once I got my head around how to go about creating it I only spent an hour on this project. I made a few tweaks to the design to ensure that it prints well (voronoi can be a nightmare on my budget 3D printer). But here are some tips: The design prints without supports, infill shouldn't matter but I used 100% as there wasn't much in it. The lower you set the layer height the better the print will be. I had mine at .2 and it printed perfectly. I also recommend slow printing speeds of around 30mm/s. 

As the title suggests it should be a nice easy print but if you have any questions just ask. 

Print Settings: Printer: Colido DIY 3D Printer, Rafts: No, Supports: No, Resolution: .2, Infill: 100%, Notes: I probably would not exceed 30mm/s print speed due to the delicate voronoi walls but if you do please let me know how it turns out. 

How I Designed This: I designed the tea light holder within Fusion 360. I then took the design over to Autodesk's Meshmixer software to convert the walls into a Voronoi pattern.
