Richmond946, very nice! Does it get in the way when shifting gears? A collapsible one would be a neat feature.

thanks. It doesn't really get in the way at all, even with a venti Iced coffee in it I can still shift fine just not exactly how I normally do.

What materials are you guys using.... everything I’ve printed in PLA doesn’t hold up to heat at all... even a hot summer day will cause it to warp, let alone engine temps

On the 3D printing front:

New bellhousing plug colors added - Green and orange


Same five colors are available for ISV and Turbo Aux Waterpump clamps.


I previously shared the 3D Printer Files (STL) in this thread so anyone with a printer can make their own. If you don't have access - I put a few up on eBay.




Those plugs if made of PLA will melt due to heat, Same with the aux turbo pump mount. Engine bay heat alone exceeds 100 degrees on turbo cars.

Looks awesome. I did this one a long time ago, which let's the cup sit a little lower I think to make shifting easier. It still kind of got in the way of shifting so I took it out after a while, but if I were commuting in it and needed my morning coffee I'd put it back in a heartbeat. Can I ask where you got the Porsche font for your model? I've downloaded a few that claim to look like the Porsche font, but they are no where near as good as yours....

Everything in that photo is polyurethane (Ninjaflex). The melting point is above 200C, so I'm confident they're suitable for use in the engine bay.

Also, I've had the water-pump and ISV clamp inserts installed for the past two years with no issues.

Default Temperature Control Unit baseplate?

Hi,

Do you still offer the baseplate for the temperature control Unit for the 944?

I really need one!

Thanks!

Testing some 3D printed odometer gears.

I'm very curious to know how well the resin holds up long term. I hardly use my SLA because the resin stinks to bad.

It works but...
Basic resins are brittle when cured.
I am trying to buy resin which has ABS stiffness which should work.

Blue - FDM 0.1mm layer height
Purple - original, injection mold
Green- first SLA test, 0.05 layer height, not the right angle



There is an issue even with SLA - the bottom hole.
It fills with resin so I have tried multiple orientations.

What nozzle diameter did you use on the blue one? The sunroof gears I did are about as small as I'd want to go with FDM (at least with my usual 0.4mm nozzle).

As for draining the captured resin, perhaps add a few indented spots to act as drill guides for drain holes? Really though for a part that small, I'd just print solid and bump up the cure/exposure time a bit.

I have tried 0.4 and 0.3mm brass nozzles and PLA, PETG filaments.
I will try to extend waiting time or plate moving distance so the resin would have more time to drain.
Results with a non transparent resin should be even better.

The funny part is that these teeth are at a small angle.

Hi guys, new to 3D printing. I know very little about the limitations other than a few obvious ones like print size.

Has anyone tried to print a door handle? Is there any reason that say, a carbon fiber print wouldn't work?

Hi Steven,

The carbon fiber filament is not true carbon fiber - it just has pieces of carbon fiber in it. You're still dealing with limited strength of the filament material, and especially between layers. Nylon filament is quite strong, but it's also hard to print. There's some other higher strength filaments out there too.

The best way to get a feel for the current limitations of home 3D printing is to just start playing around with one. They're quite affordable now and the bugs are mostly worked out.

I find 3D printing to be great for prototyping - it's very cool to sketch something up on the computer and have it exist a few hours later. Revise and reprint until you have an optimized design.
