I take my final combined STL file into Simplif圓D and make sure that my dimensions are still correct. In the end I am left with a combined pair of pumpkins with a hole between them that lets the LED candle light leak through between them, which I found enhanced the randomness of the candle flicker and reduced the digital unnatural look of just one of these electronic tealights.Īt this point, I am ready to set up my print. However, I want to print these as a combined decoration- so I take the models into MeshMixer to do some boolean combining and remeshing. If I want, I could go ahead and just print these pumpkins individually. This makes the workflow non-destructive and dynamic.Īt this point, I have my pumpkins complete. Where possible, I prefer to leave modifiers not-applied. In Blender I then import the STL file, split apart the faces, and add the Boolean modifier set to ‘Difference’ on each pumpkin.
What I’m going to do is remove the faces with booleans, so the model I want is what is going to be removed from the inside of the outline- essentially the same shape as the chunk of pumpkin you would cut out of an actual Jack-O-Lantern. I sketch up my pumpkin’s faces using simple lines and 3 point arcs, then extrude the insides of these designs.
Fusion will allow me to draw the faces to scale in sketch mode using its powerful tools for dimensions and constraints like mirroring. To create the faces of my pumpkins, I now open up Fusion 360. Working this way allows me to easily change the shape of my design by just modifying the outer shell of my model, and then Blender will dynamically create the thickness of the inner walls of our 3D print based on that surface. At this point I also add the Solidify modifier, and give my pumpkin a thickness of 3mm. The tall one will be my excited happy Jack-O-Lantern, the short one will be my downtrodden sad Jack-O-Lantern. I can then duplicate my pumpkin, and edit that one to be more short and stout. I do the same to make the stem, and am left with this: I add some more edge loops, moving and scaling them into the shape of my pumpkin, before finally selecting every other edge loop and scaling in. I found that roughly 75mm at its widest and 75mm tall looked good for my pumpkin. So, I create two 16 sided circles of those sizes and bridge them to create the faces for my base, and extrude upwards. I’m working on a Maker Select v2 which has a 200x200mm build area, and I know that the standard diameter of tealights are 38mm, so I roughly figure that I was my base to be 50mm with a 38.5mm hole (a little wider than the light to provide some tolerance, but of course we can take a file to that hole later if it needs to be widened).
Because I’m modelling polygonally, the easiest way to achieve this is to create a 16 sided polygonal circle- I can then select every other edge and scale them in before applying Subdivision Surface smoothing (TurboSmooth for the 3DS Max folks) to achieve my pumpkin look. I know that I want a symmetrical design for my pumpkin, and figure that 8 ridges will look best, as from the front that would mean a central ridge roughly for the nose and two more for the eyes. In the Scene settings I turn on Metric, and set my units to Millimetres.Īt this point, I start modelling the base of the pumpkin. The first thing I do when opening up Blender is make sure that my scene is set to the correct units- we’re going to be 3D printing our model to scale in order to fit some real world LED flickering tealights, so we have to make sure our units are correct.
#Halloween 3d 2018 software
Both are great free modelling softwares for Hobbyists, and Fusion 360 is an awesome piece of software for designing hardsurface and mechanical items, but seeing as this project was more organic modelling I went back to my traditional polygonal modelling roots. Before modelling I made the decision to go with Blender3D rather than Fusion 360 for this project.
