heinzboehmer's 2002 Topaz 6MT Coupe

On another note, I still can't get over how cool the PET-CF prints come out looking. Blows my mind every time.

Here's a third of the cabin air filter housing:




(Yeah the amount of supports needed is insane, but want to print it this way to orient the layer lines in the direction that will see the largest loads. Mostly worried about me or someone else leaning on it when it's installed and snapping it in half.)

Maybe I missed it, but what printer are you using? Do you find that the PET-CF wears out the hot end faster? Also, are you concerned about fumes at all?

You just need a hardened nozzle… And air filtration on the printers exhaust

Using a Bambu P1S, but I reeeally want a dual nozzle printer. That upgrade will probably be coming soon, but this one has been great for now.

And +1 to both things that Obioban said. The P1S has a filter on the chamber exhaust fan, but I still keep it in a separate room in the garage level that doesn't get much human traffic. I'll open up some doors to the outside if I'm printing stinky stuff for a long time and that seems to keep the fumes under control.

I really have no idea how frequently I should be changing my printer's air filter.

Can't wait to add this next year to my CoreONE: https://www.prusa3d.com/applications...h-indx_243519/

Feels like it should have most the benefits of multiple nozzles, but with up to 8 different materials.

Speaking of printing, here's what the gasket situation ended up at:



Everything that isn't red, green, orange, purple or dark blue is a gasket.

As discussed previously, had to add those bumps to the firewall plug so that there was enough install clearance for the cabin air filter housing, which means they also needed gaskets.

Since there's more space to play with here, I came up with this:




Added some drafts to these bump gaskets and made sure the thickest portion was a flat surface. This should make printing them way easier than the others.

Similarly, the housing gaskets are a crazy shape, but there's space under there, so I just extended them out until the entire thing was flat on one side:



Plug bump gaskets are installed using the same T slot interface as before, which does not work for the housing gaskets, so those are getting glued in. Fortunately, the geometry of the housing gaskets should hold them in well, so the glue is just a backup.

Printed out the bump gaskets first and WOW. I have no idea what I did different to before, but these came out pretty much as perfect as I can expect from a part like this:



You can see the difference in print quality compared to the other plug gaskets I printed in the past:




Housing gaskets print is wrapping up and they're looking as good as these, so gonna reprint the rest of the plug gaskets and swap those over later.

Have also saved the Bambu Studio projects so I can reprint these in the future if necessary. I've noticed the filament only likes to stay dry for about two hours, so I'm having to throw it into the drier in between prints. One of those driers you can print directly out of is definitely going on the Christmas list.

And they work!



Just gotta get through the rest of the printing and assembly and I'll have a finished project

Finally.

Man, that's super cool.

Am definitely eyeing the Prusa machines as an upgrade to my current one. But I don't need to upgrade, so process has been slow.

I love that PET-CF, I print every test project with that because it just looks so goooood 😂

Thanks for the info! I have a p2S but it’s in my office, so I haven’t ventured out beyond PLA yet.

Im also far behind you in terms of CAD ability! You’re next level!

It's amazing, isn't it? I was originally planning on painting these parts to match the stock ones, but they look so good straight out of the printer that I might not even bother.

Yeah fair enough. I wouldn't want to be working next to the printer when it's printing these materials.

And I still kinda suck at CAD, to be honest. I'm very stubborn though, so just spend a ton of time staring at the screen trying to figure it out


I was actually just talking to a friend about the time I've spent on this project. Realized the CAD suite stores the entire version history of a document, so I can estimate how much time I spent designing this stuff. Not a perfect representation as the version history is just a list of changes with their associated timestamps, so have to do a bit of guessing to figure out if I was working in between changes or not. Good enough though.

Anyway, estimate came out to ~150 hours of active CAD work. Damn, that's a month of 40 hr work weeks... And that doesn't take into account any time in the garage. Woah.

Now imagine you’re managing a mechanical engineering team and need to estimate the time/resources it’s going to take to design a full product that doesn’t exist yet

For this exact reason my first maxim of project management is (somewhat tongue in cheek) "all project management is founded on lies"

In the thick of planning for next year at my real job. I feel the pain...

Adding up hours is like adding up receipts but worse.

Ya, don't do that, lol.

I just had to add up the costs for the touring CF doors for customs... wish I hadn't
