    Slightly off topic, but what's your printer setup and settings? Material? I'm pretty impressed by that pattern on the inside of the lenses, is that designed in or just your infill setting? Also what kind of post processing are you doing?

     

    These were done on a Stratasys Objet 350 polyjet printer in Vero clear. The pattern is modeled in just as it was printed.

  2. This is the design I've settled on after months of analysis; it wouldn't be THAT difficult to remove the forward components and make a roll bar. I think just as important than the design is the quality of construction. Having large gaps around the main hoop perimeter with no tie-ins to the body the gains you see will be negligible.

    my first thought also but the pocket they sit in is pretty shallow. dont think you will get much depth if you go down n with the vents. my 2 cents would be to make it a single raised vent kinda like how they do on top of fenders to release wheel well pressure. the one you developed looks exactly like rear window louvers, which if you have them and like them then your spot on. i dont care for them so thats were my dislike comes in....i will say though im very happy to see someone doing something with the s130's. so keep doing what your doing!!!

    Thanks for the inut G-Tech and others. I was concerned with flow first, looks second. Good to know 260DET's experience matches what I suspected would happen.I didn't run a sim with the louvers reversed, but there definitely is not as much room in there, plus garbage gets funneled into your engine bay when stopped. My design won't stop that happening but it won' encourage it, either.

     

    Now, onto something solely cosmetic, I've been working on 3D printing some turn signal lenses. Slightly ricey but pretty wanted to try something with the clear filament.

  4. Lately I've taken aim at designing a better hood vent setup for the 280zx. First I created a blank template to ensure I got the shape correct (pic 7). The stock vent passenger vent is mostly cosmetic, with a very small actual open area for airflow (pics 1&2).

     

    Opening all the vents releases much more air (pics 3&4) but sending it straight up creates all sorts of turbulence issues. Flow: +178%

     

    Putting louvers over the opening starts the air moving the same direction as the outside air (pics 5&6). A roughly 20* angle appears to get the best Venturi effects. Flow: +400%

     

    You can see from the cutting\drilling guide how much more area will be opened up to airflow. I 3D printed a set, slapped some black paint on them and they're ready to be installed. I did add a small ridge around the border to stiffen them significantly.

  5. Thanks Lance. It's not designed to work with any of the stock pieces because there's not much of the original panels left on my car. I'm sure they'd be popular but I really don't have desire to make for-profit parts; this project is my way to test my limits and have a little bit of fun, money be damned.

  6. So, in the process of rewiring the whole car I wanted to simplify all the electric controls to one panel in the center console. Originally I planned to CNC mill it, but thought I'd try a different approach:

     

    Drew it up in SolidWorks and exported the stl file for printing:

    Print in-progress. The hexagonal infill pattern keeps materials and weight down while still being super strong:

    After printing, the toggle switches were added and the wiring started:

    After the toggle switches are done, add a kick ass starter button, slap on some paint, and voila!

  7. 2004 Ford Excursion diesel, tows like a dream and gets decent fuel mileage. I picked it up for just under your budget.

     

    Similarly, I use a Suburban. I know you said you don't like trucks, but it's awfully nice to lay the seats flat and sleep comfortably for a couple hours on a road trip.

  8. In the process of rewiring my car, I decided that anything worth doing is worth doing to complete and utter overkill, so I made a billet aluminum box for my relays. 

     

    Squaring the billet.

    Milling out the pocket.

    Mounting posts for the 4 relays, countersunk and threaded from the back, plus the cutout in the bottom for wiring.

    The only thing left to do is CNC engrave the cover.
