Hi Mark,
Not sure what process Shapeways uses... might be wintered or sand cast.
This is just a rendering... gonna make a change at the connection and offer them at cost... we’ll see if there are any takers...
Should be around $23 ish.

Cool idea I may jump in for a few sets.

Ok fellas, Here are the rear trailing fenders for a Standard wheelbase car. It hasn't been printed yet... so I wouldn't advise buying multiples just yet. I am going to order one in steel... which I figure will weigh about 19g... So it will save a few bucks on tungsten. Rear Trailing Fenders |

Does it inset into weight pocket?
Cut some of the body off and add this?
Cubes in the space provided?
Which option on Shapeways do you think will be the heaviest?

Hard to explain but... On a normal build... those hooks will go where the cubes on the extreme left and right in the second row would normally go. So the rear trailing fender can attach to the wood inside the weight pocket as well as attach to a couple of cubes that are directly behind the axle spar on a normal build. Like this: See the hooks? I think the steel is heaviest... the steels are all the same except for the surface finish. I'm going with the cheapest steel probably or maybe the gold colored steel for a few bucks more.

  I think that I have an idea of how to wrap a graphic on these compound curves... But I’m interested in hearing alternatives. Thoughts?  |

Do you know the volume of the finished part?

Do you know the volume of the finished part? Sure... Ummm... which part are we we talking about? The rear bumper? This program is dope! If I load in the different materials/ densities... it’ll even tell me where the COM is... I think... never tried it. That is is how I figured out how much a steel bumper would weigh though. |

Ok, might be time to call in a favor from a buddy. Let's make this a forum project.
My buddy has a 3D printer that does tungsten and titanium.
How would we design this is it was made of tungsten? I am assuming a solid for the unique geometries with the flats being filled by cubes? Make an "L" for the actual wood body that serves as the spar for the rear wheels (short leg of L) and a spar that reaches out to front wheel (long leg of L)

I think it comes out to about 2.54 cubic centimeters for the rear bumper/ trailing rear fenders... So... if we are talking sintered tungsten at say 17.5 g/ cu cm... that is like... ummm... 42g? ish |

My thoughts are a bit different.
If tungsten, and not standard wheelbase, I would:
make the furthest area behind the wheels as thin as possible.
forget about the rear taper.
Make it so it goes all the way across the back of rear spar Have it loop down and around the bottom inside of the wheel
Think rear weight with cubs and area above and below rear wheel all in one. Or, for car guys - this is like the modern cars where you drop your motor, trans, and suspension (or lift the car body off) to work on it.
Body would be CNC'd slightly narrower except for axle spar area.
Unit would slide up under to be glued in place.

The steel/bronze blend that shapeways uses would only be about 40% of the equivalent in Tungsten.

Hey Joe, which of your front and center fender sets would you recommend using with the trailing fender?

I guess it could be the Standard setup I have on Shapeways...
But I have a new thing that I’ve been working on with Eagle...
It hasn’t been printed yet...
Just gotta flip the switch...
Any takers? Gunna list it at cost.
The clearances will be a little looser than normal around the wheels... .06”
But.. I think it will be a fun build.
Gotta figure out a name for it too.

Let me know when you have it up. I’ll order all at once. (Laser-Eagle?) |
