COMPUTER-AIDED DESIGN (CAD) MODELING:
At MotoIQ, we have used computer-aided design (CAD) and 3D printing to mock up a custom turbo manifold for Project S2000. This enabled us to locate the turbo exactly where we wanted and model the flow characteristics before having it investment cast out of 347SS.
There are a lot of CAD software options out there. Solidworks and AutoCAD are two very well-known and popular options, but cost $1,300-1,700 per year. Meanwhile Fusion 360 costs $495 for the professional, and is free for hobbyists if the user generates less than $1,000 in annual revenue. There are various other free software including TinkerCAD, FreeCAD, SketchUp, Onshape Free, Blender, but many are limited in their functionality compared to the software that you pay for.
I decided to go with Fusion 360 For Personal Use from AutoDesk.com due to the power of the software, the support and tutorials online, and it’s free for me as a Hobbyist since I’m designing parts to make my car better and my life easier.
Next, I had to learn how to use the software. I did this by searching YouTube for Fusion 360 Tutorials. I found a really good 3-part tutorial by Lars Christensen on how to make a simple conduit box.
After getting the basics down on how to use the fundamental tools of sketching geometries, cutting, and extruding, I found a more advanced video on making snap fit cases. Click the link.
With these skills, I made my first design. A little bracket that mounts a Raspberry Pi to a screen
After a couple hours of print time, I successfully mounted a Raspberry Pi to a Capacitive Touch Screen with my design.
My next design came out of frustration. I needed to adapt a 1.75” shop Vac to a 1.25” pet attachment. I had to return 3-4 different assorted vacuum attachment kits purchased from Amazon because nothing worked. I used my newfound skills to quickly draw up this simple adapter.
With less than an hour of print time it was finished. I was ecstatic that within a few minutes, I solved a problem that took me days of purchasing and returning parts that didn’t work from Amazon! This endeavor is already helping in many ways.
Now that my comfort level with designing and printing was at a good point, I was ready to tackle the real driving force behind this entire effort, the NSX door frame.
