Bluetooth Mouse Mimic - Process Sketching and Planning Projecting Each Side onto a Round Shape, Subtracting, Adding Final "Normal" Model Initial Prototype The first thing I did since finishing my model was to try out printing a small low-resolution version of it to see how the basic structure would come out without very many supports. I'm happy with the result and ready to print the modified version of the object as well soon. Modifying the Model Once I had my normal mouse model finished I began to modify it entirely. First I bent the cover piece open like a mouth. The details involved fleshy webbing at the corners of the mouth, gums and teeth, a ribbed texture on the uncovered parts of the mouse, and different text on the DPI button . Combining everything into a valid polysurface was another time killer, but eventually, I had two versions of the model: the normal mouse and the transformed "mimic" monster.  Final Modified Model and Renders Prusa Set-Up As of Jun...

  Some initial renders of my object while I work on preparing it for 3D printing. Changes may still be made to the model before the final print, so these are the initial tests.  The process so far for reverse engineering this object has had a lot of ups and downs. The modification I'd like to make to the object is still in progress, but I focused on having a solid replication to build on first, represented below. One of the more difficult aspects of this has been managing the surfaces that make up each piece of the object and trying to make them seamlessly combine. When I begin to print the object, I'll see if there are any more changes I need to make.  I may need to return for another technician appointment once I've gone ahead with my "modification" ideas. I've included images of the work in progress (essentially opening up the top of the mouse and adding teeth and flesh textures along the seams like a mouth) below the renders of the unmodified object. Addin...

Though I have finished the replication of my object, I didn't manage to find the time to make all the additions I wanted to and transform the object into a little monster. I realized that my concept was a little more ambitious than I had time for, especially when I took into account the time I'd be devoting to finding a suitable workflow. If I get a chance in the time between my appointments and actually printing my object, I want to attempt to develop it further, but this is why I decided to start with the basic replication and try to build on top of it later.  Here is the  link  to my presentation on my reverse engineering process. Below are renders of my object with a matching material as well as the photos of the original.

I started to model my mouse by measuring what I could and scaling other parts of the model to match. For the most part things lined up and allowed me to project individual faces like the top view of the mouse onto a rounded shape (distorted sphere). From there I spent some time extracting lines and sweeping edges together to make the first piece of the object, just the top piece of black plastic.  The trouble I am having now is in combining the rest of the mouse with this single piece. Building a rounded surface was simple enough but the curve only extended in one direction, and the rest of the object had so many interacting curves that I couldn't wrap my head around how to approach modeling it with the same approach of building surfaces from lines. I tried to build an entire object by subtracting pieces from a sphere but reached a similar roadblock where it wasn't exactly what I wanted and I needed help to visualize how to proceed. At the moment I am confused and progress has ...

Here is the  link to my new slideshow, with some extra detail about my concept for this project.   As I attempted to get started on my reverse engineering project (accurately replicating a bluetooth mouse to later modify and build on top of) I immediately ran into some trouble with my workflow.  I haven't been able to figure out how to approach the many complex curves of this object in Rhino. I began with making drawings of different angles of the object, to attempt to trace and scale to match the measurements I'm taking along the way. My major roadblock here is that A) the object is difficult to tackle or begin to outline even with six different views of it and B) once I have some basic outlines (not entirely accurate yet, just to try to create a surface from) I'm not sure what to do with them.  I've tried to explore sweep 1 and sweep 2, but wasn't sure if they were applicable to my project as-is, and had trouble understanding how to modify my outlines to make ...
