Alfa Romeo 2600 Spider Borrani style wheel (Prusa Fusion 360 course)

I used my Prusameter points to sign up for the 3D Modeling in Fusion 360 course as soon at it was available.  The second example project is to make this wheel, and at the end of the step-by-step instructions, the course invites you to upload your version as a remix of the original.  So I did.

The course instructions instruct you to trace over the original cross-section drawing from Borrani, rotate that cross section to create the hub and rim, and then trace over a different photo of the wheel to lay out guide lines for the spokes.  They say that this project should take 1-2 hours, but I found it took a lot of fiddling to get the spokes right, so it took me a little longer.  But even so, it's kind of amazing how quickly you can go from a blank sheet of paper to a really nice looking model.

I've included both the .stl and the .f3d file here.

The instructions recommend printing this on a resin printer, but I figured I would give it a try on my MK3S+ anyways. It turned out to be an H.R. Giger-esque nightmare. I guess much like a bear riding a bicycle, it's not so much that it's done well, it's that it can be done at all.

(I scaled it up by 400% and printed it using Numakers PLA and a 0.15 layer height, and organic supports.  I'll recommend using the “Classic” rather than “Arachne” perimeter generator, as well.  Good luck!  There's something actually kind of satisfying about removing the nightmarish supports.)

Once again, if you're interested in the course, I really enjoyed it and recommend it.
