Previous owner had some ghetto looking mesh screwed into the dash covering the windshield defroster vents, and I finally got around to sorting it out this weekend.
Has anyone thought about printing out a flywheel lock? The geometry seems like a prime candidate for a print if you ask me, provided that plastic is strong enough...

I've thought about it - I have one and could model it up and post the design here.
Not sure about strength though - likely sufficient to get the belts lined up, but I'm not sure it would survive breaking the crank bolt free.

Might be an interesting test of something I used to do with balsa/carbon fiber stuff. Been thinking about applying it to 3D printing but hadn't had a use-case until perhaps this.
I'd carve out narrow channels in light structures and fill them in with a mixture of JBWeld and shredded CF tow, sometimes bulging in spots for drill/tap. I don't think the shredded CF would be necessary for this as weight wouldn't be an issue and you could use a thicker channel of JB, but perhaps a washer or something from the hardware store could be used for the actual engagement of the flywheel, leveraging a supporting internal structure of cured JB, with the printed body providing the rest of the mechanical fit.
KVDR, can you print the OEM plastic rear wiper delete plug that goes in the hatch glass?
I don't have a design or part to model from, but I am confident that I could print a functional plug. It would take a bit of sanding to achieve the right appearance.
I've been using a new material called ApolloX which is an ASA (Acrylonitrile Styrene Acrylate) polymer - it's similar to ABS but has 10x the UV resistance and is easier to print. It does produce some odors during printing like ABS, so I am keeping a window open to minimize harmful particulates. http://www.formfutura.com/apollox/
I had to print some replacement parts for my printer (Lulzbot Taz5) that were starting to crack. Original parts are ABS. I took the opportunity to beef them up a bit, while also upgrading to the ApolloX material.
This is an idea that came up in another thread. I'm not sure if anyone has suggested it so forgive me if it has. But the plastic insert for our door handles seem to be NLA. I think you may get some interest from people looking to replace theirs. I know I would be interested.
Off topic from my 951 track car, but figured I'd ask anyways. I managed to break the throttle on my brush saw, which of course they no longer make. Is there anyone out there that could make a replacement of the attached part? It's about 1.5 inches long. A new saw of this type costs more than a set of track tires, so I'd really like to get one made. I could send the original one.
Thanks,
Buzz,
Hm. On the face of it, it seems like that should be a fairly easily printable part. I wonder how much torque/pressure is put on it though. Looking at where the original failed, I'm not sure how much better a 3D printed part would do. Of course, some plastics do get brittle over the years, so that's maybe what happened with your part there.
Anyway... Back to the original reason for this thread...
Like most every 944 these days, my car doesn't have the original cover over the clutch examination port, so I printed a couple to try out.
The deeper one has better purchase on the friction fit, so I'm going with that one. If anyone wants the STL files for this, they're welcome to them...
