That's the one that won't work for my car, right?
I forgot all about changing this design to work for my jalopy.

[Bucketlist]

On the subject.... I started prototyping this funnel the other day on my new (cheap) Ender 3 v3 SE. My 81 SC Turbo the hood hinge is in the way of most funnels so I'm working on a work around. I printed this in PLA and I should try at least PTEG.

I am tempted to try and sell them.....it took a few days of design and a few trials...think anyone would buy one?

Throw the STL on Cults. That way people can buy the STL and print their own.

No way to know for sure other than to post a price and ask people. Since you’ve already invested in the design for yourself, printing for others is just a material and admin game.

Don’t know where you’re based but if you’re in Europe at least there’s no tariffs for us Europeans.

Has anybody made a 3d model or STL of a 964/993 intake manifold base modified for 2 bolt heads?

Adapting this



but with the footprint of this

[LukasM]

I haven't seen a 3D model but there are a few companies that make these adapters in aluminum, which I think is the right material for this application. Even with modern filament like PPA-CF I'd be worried about longevity due to close (with a phenolic spaccer in between) contact with the head, vibrations, etc.

Adapt is a bit cheaper than Islandworks

I only the GT3 intake version but I'm pretty sure they have one for the 964 as well since the owner Jonas has a 2.7 or 3L engine with 964 intake.

For what it's worth, I tried making a longhood heater duct. After a lot of prototypes, I got it to fit nicely.

I made it out of ABS and it just did not work. The proximity to the cylinder head and heat cycles warped it, and made it soft enough while driving that the bolts became lose and backed out. I did not try PAHT, which might have faired better, but got tired of the effort.

I also made a oil filler after spilling oil all over using my old funnel. Having it secured to the filler pipe is so much better.

[Showdown]

I’ve played around with a lot of filaments trying to find heat tolerant ones and what I’ve found is that PA6GF or CF, PAHT-CF or PET-CF are all great.

Bambu has a wonder filament PPA-CF that is stable up to 227 Celsius and has properties that rival and sometimes exceed aluminum. But it’s $150 a kilo!

There are now a few different brands for PPA-CF, all very similar properties, probably many produced by the same suppliers anyway.

Siraya Tech even has a "core" version, where the carbon particles are wrapped inside an outer layer of PPA only, which theoretically gives it better layer adhesion. Also better price at "only" $88 per kilo.

MyTechFun on Youtube has some good comparison videos, I think all 5+ different PPA-CFs he tested hold up to 220°C heat and should be strong enough for most applications like heater ducts.

Yea, I would buy a reasonable priced one that works for my 85 911. And if it could be disassembled to fit in the trunk easily that would be even better. I take long road trips, and I have to add oil on the road after 1,2000 miles.

Please PM me with a price.

I printed up some plugs to block off the heater duct holes in the engine tin (Excuse my crude novice design skills) using the Bambu PAHT-CF and I was happy with how they turned out. While we haven't hit summer temps in the northeast yet, they've held up over the last few weeks of driving with a few days at 83*F ambient temps.

Working on a funnel for my Turbo SC. This second prototype is getting close just need to increase wall thickness in maybe PTEG next time. Used TPU for the connection to the filler neck and I like the feel of that.

Wanted to share files , Fusion360 & STL files, wanted to share them amongst the forum . who can i send to ?

[Bucketlist]

Most members who want to share their .stl file just post it here, or on one of the 3d printing websites like:https://www.3dnatives.com/en/thingiverse-platform-190220204/

[Bucketlist]

These guys are into all the expensive exotic filaments and have been printing parts for NASA. See their selection: https://visionminer.com/collections/filament

Thanks, will post and see what happens, i hate joining group, sites and fostering spam...
Love the new fillaments that just BambuLab are coming out with, let alone NASA
Great conversations ...

Shame i can't post images easily, sorry don't have amoth amounts of time ..
three posted stl's on https://makerworld.com/

Ping me for fusion files, happy to share, will post the remaining projects later today

Hi all, just getting things going.

Here is my rendition of the air duct which feeds engine air from the fan to the crosspipe of the '89 Carrera heating system (the cross pipe feeds air to the air exchangers).

There is no fan in this as I put upgraded footwell fans (another thread I added to somwhere...forget where) with significantly stronger motors than the original Bosch pieces of junk.

I also rewired the autoheat fan control system so at low heat settings it is just the air from the engine fan (through this duct) and the footwell fans kick in only above level 3 on the autoheat control knob - with the standard 3 speeds, highest kicking in only at level 8, 9 and 10. The autoheat and AC control knobs were all standardized to use the autoheat knobs and relocated to my custom 3D printed console shown elsewhere on this thread.

This part is way too fun, lots of curves, had to master lofting in Fusion 360....several time I took the Lord's name in vain...sigh.

Looks good

And yeah, lofting in fusion is like playing the lottery, never know if it will work or not. Hell sometimes it says it works, hit accept and then it fails.

Nice work. A lot of ppl, including myself have been asking for one of these for the SC's, the fit on the part sold by pp is horrible. would be very similar but need a indent where distributor is
