christmas ornaments

Christmas ornament project

After taking several months off from practicing on rhino7, I realized that I soon had an OBDF class coming up next semester, and I really needed to get warmed up. I decided that 3D-printed Christmas ornaments might just be the coolest thing ever, so here I am getting back on track in Rhino.

Firstly, I used my command cheat sheet religiously. It was a crutch that I slowly had to wean myself off of. But after about an hour more of messing around trying to get the hang of Boolean unions and Boolean differences, I came up with a design that should work out.

I wanted to create something circular, something that could still look great on my mother's tree and would match most of the shiny white and red bulbs she brings out each winter. But that being said, round shapes and 3D printers can take a bit of finessing, and if you're in a pinch and don't have 7+ hours to dedicate to each print job, this should be the project for you.

I decided to slice the sphere into two segments, with details poking out of the sides so that way you can see the intricate snowflake details that I created simply by drawing them out with the para line tool, extruding and capping each of them, and then utilizing Boolean difference to take small chunks out of each of the "plates" as we will now call them. each of the plates is designed to slide into one another easily, and then I will finish the job with some super glue to reinforce them, hit them with some spray paint perhaps and to top it off, some shiny red ribbon.

here's where I struggled; the mock-ups were not quite right the first time, as some of my math was not correct, and although the length of the pieces could slide in properly, the width was all wrong. However, this was simple enough to fix, and I corrected my mistake immediately by copying and pasting the segment that will be subtracted from my plates and then using the Boolean difference tool to make that pocket perfect, down to the atoms even.

I continued and made some easy renders for you to see the finished product; it looks great in the Prusa slicer. Hopefully, I will be able to most the finished product on here soon!

Marina Dawson: Project Proposal

Project Proposal For this upcoming deadline, I would like to create a large laser-cut tapestry on black paper that is roughly 3ft by 2ft. I would like to create imagery based on one of my favourite movies, Howl's Moving Castle, by Studio Ghibli, and laser-cut it onto paper to be hung with a poster hanger. The designs will begin from the top left and work their way down to the bottom right, as the tapestry tells the film's story with certain elements from each major scene featured in each section. I have chosen this movie because it was the first anime I watched as a kid and the catalyst for my love for the medium. With a beautiful soundtrack, a star-studded cast of voice actors, and, of course, Hayao Miyazaki's creative direction, this film is an instant classic for me. I am incredibly excited to begin the design process in Rhino and create something beautiful. After reviewing screenshots from the movie, I examined some of the recurring design themes, such...

The beginning stages: To begin with this project I first begun searching the web for inspiration directly from the frames in the film. I enjoyed finding certain themes in the designs that stood out to me such as flowers, stars and varying celestial patterns and ornate crown molding from the castle and the towns the film was set in. Drawing from the concept art was also helpful because it allowed me to think about the bare bones of the design and how I could begin to simplify the process into rhino into a design that would not be too ornate on the cutting bed, which could run the risk of loosing details or causing a fire. In the end I decided to come up with a sketch for the first section of the tapestry, which ended up evolving several times. My sketch: I also chose to research tapestries from the same era that the film was set in, I decided that the main element I wanted to appropriate was the boarder from 19th-century English hard point tapestries designed t...

Project 2 proposal

I propose to create a second bespoke item, this time however I would like to learn how to use 3D scanners to CAD. I have always wanted to utilize this skill to create a highly intricate object which could become piece of fine art. I hope to create something sculptural but still obviously true to the medium of 3D printing, I do not plan to paint or sand the object. I also could be open to showcasing it as part of the graduate show this may when I convocate! My idea is foster the current research I have been doing in my drawing art practice which is about the intersections between ecology and feminism. specifically Eco-Feminism. Because of this, I would like to create 3D scans of my body, which is similar to how I also take imprints of my body in organic materials onto rag paper, and splice the scans into segments of limbs which can be hung flat on the wall. I would like to use perhaps a resin printer for this process or the new larger Prusa printer. I also plan to design spot...
