I tried several times to order the TPU (black) ones and it keeps saying unavailable? Am I doing something wrong? I want the 2.25" one also. Thanks Matt!

Make sure you select black and not gray for TPU. Each material only has one color. I will update the description to let customers know.

Matt I placed an order last week, will I get an update when they are sent? Thanks

Yes, I'll let you know when they ship; the print farm reports their usual lead time is about two or three weeks. It looks like they've still in the print queue but should print soon.

Hey there! That's awesome that you've found a way to keep the momentum going with your voltage regulator plan by venturing into 3D printing interior parts to raise funds. Reverse engineering some much-needed parts for a classic car like the '66 Dart sounds like a fantastic idea! Armrests, dash vents, and A-pillar trim are definitely essential parts, especially if they tend to crack often. You might also want to consider items like door handles or other hard-to-find pieces that enthusiasts often struggle to source. Your attention to detail and dedication to problem-solving will definitely pay off – keep up the great work!

I was going to do a glove box liner, but it looks like the print farm can't fit it in a FDM printer. Their resin printer is apparently up for the job, but not at a reasonable price. So now I'm working on armrests.

Armrest pads model for test fitting in progress. Although meant for a front armrest, I think these may also work on the rear seats if you want to delete the ashtrays.

I'm not in the market, but I have a question: why are these shaped differently to the originals? The originals had curved long sides, and these have two straight lines—a short one and a long one—connected at a sharp corner.

Too many people who were born on third base actually believe they've hit a triple.

The vents I had on my car - these are a junkyard set as the originals cracked, and may be aftermarket - have a straight tube that abruptly dumps into a short rectangular duct. There's an abrupt edge transition there. I decided that instead of copying this, I would do a gradual flare-out for smoother airflow. I also made the vanes curved like turbine blades instead of flat, both to smooth air flow and because the curve would make them a bit stiffer.

Due to the limits of 3D printing, having the vanes inset away from the upper surface would have had problems with the vanes sagging while printing, so I moved the top of the vanes to be flush with the top of the vent. I figured that if the part wouldn't fool a restoration judge, I might as well see if I could improve the design. The one I was working with is either an aftermarket copy or something Chrysler needed done in a very short timeframe; it was clearly designed more to economize on mold making than anything else.

No, I mean the edges indicated by the green arrows here. Curved on the original, straight-with-corner on the new:

I was trying to tell if the intended shape was a straight line or a gentle curve, and it looks like I guessed wrong. However, some details of this model are pushing Freecad to its limits, and changing that line to a curve is likely to break a lot of things in the model.

This may come up with a couple other items where I have to tell if a feature is the original intent or if I'm dealing with a warped part. For example, I'm trying to figure out if the top of the armrest was supposed to be horizontal, or if the angle is intentionally greater than 90 degrees.
