About this model

Similar to a previous design ( but much better ventilated. I'd been wanting to use a Voronoi pattern in a project and discovered an online resource for converting 3d models into printable "Vorinated" bodies ( The site has its limitations, but it's free and easy to use. The alternative is to use a Voronoi plug-in in your design software which will give you a lot more control. I printed this vertically without a raft or supports. It's a good idea to bury the model into the build plate a little bit (say 1mm) so you have a decent base layer to start from. This will string a little so maybe turn down your hot end temperature or up your retraction. I did neither and it turned out fine.
