Well, this is a prototype, so to save costs, I'm going to use PLA first since it may still need some tweaking in order to accept the stock shift plate. ABS will cost $20 more in material costs roughly...but trivial to pick one material vs. another.
Yeah, don't want to break the bank on the prototype. I had no idea PLA was that much less. I know TPU and PVA are expensive, along with TPE.
Actually, those flexible materials may be a better fit. ABS has a but of give. Mix it a bit for TPU or TPE, and no wrapping would be needed, but probably an additional $40. I'm just not sure about the effect of UV. Still, if I were going to make it, I'd make it with an aluminum frame, and mold something like TPU over it. No corrosion, not brittle, and no cover needed. But I know little of such things.
Well, I'm still prototyping in PLA. Hopefully the next one is perfect, but it may require 1 more. I have to wait about a week to get it shipped to me. The thing about those more exotic materials is the cost. Also looking into console trays.
Down the road, I'd probably want to make a replacement vent/heater/stereo section that angles from the end of the shift surround to the top of the stock location and make it handle a double-din stereo and use the stock vents and climate controls ... but that's real far down the road.
