Mouse design, Fusion work and filmic color management addon for Blender

So after finishing modeling this mouse design in Fusion360, it was a worthwhile learning experience and I’m happy with how the 3d print turned out.  After looking in more depth are other mouse designs, Logitech’s especially I’ve an appreciation of the complexity and skill involved in creating a tool that has become something of daily use and taken for granted.  What makes this design unique is the touchscreen, but in all honesty if this was to go into production I would redesign it, making it about 40% more compact, the side buttons larger, with buttons on the side, LED lighting and textured surface patterns.  It needs to look as visually sophisticated as a Logitech design.  I’ll explain in more detail in the coming days how the concept functions.

What was lacking in my portfolio was evidence of knowledge of injection molding and the manufacturing processes involved.  It has a constant 2mm wall thickness with ribs with a thickness at a .5 ratio as advised back when I visited a Takata plant in Bavaria.


With further sanding with Z-Poxy to fill in the crevices smooth out the surface it will eventually be ready for spray painting with the aim of making it indistinguishable from an injected molded product apart from micro details.

 

Now that I’m at a stage where I’m comfortable using Fusion, less mental energy is used concentrating on how to make the desired shapes and it becomes more enjoyable when making something creative.  This watch design will look great, a level above the Sioux watch that never really looked top quality and high end in terms of design.

 

In Blender Cycles, I re-rendered pretty much everything since buying some HDRIs, a plastic PBR shader and discovering the filmic color management addon, it’s amazing.  Render time is increased, it takes more samples to deal with graininess and it’s worth the extra time when the end result, for interiors especially are more realistic thanks to a larger dynamic range.  Before my work didn’t look quite right and could not understand why as you can see below in the rendered image below.  The differences between the two renders speaks for itself, it’s like they were made with an entirely different renderer.  It’s not bad for open source software, is it?  Who needs to spend €3000 on 3dsmax, when Blender is free?

Mouse Update and Roman Coin Display


I have collected a few Roman coins over the years and always wanted to show them off.  Now with a 3d printer I can do just that.  A couple of the components are 3d printed and in the next couple of days the rest will be printed out.  With some Z-poxy brushwork, sanding and spray painting it will look like it came right out of an injection moulding.


An update on the mouse design, it still hasn’t a name.  The trickiest parts have been figures out more or less, that being how the touchscreen and buttons will function.  The six side buttons are return to the their original position using springs, although I had considered using rubbery plastic like that used for console control buttons.  How the parts will fit together is a choice between using snap fittings and screws.  Finally, when it is close to completion, some ribbing may be required to counteract shrinkage with the material of choice being either PLA or ABS.  Ideally, if this ever goes to production I would want to use PLA.  The material is non-toxic, environmentally friendly and recyclable coming from sustainable sources, that being starch.  From my experience of using PLAs, not only with 3d printing the warping is less of an issue and PLA last forever as long as it is kept away from outdoor elements.
