Water Intrusion to Fuse Box - Whiteface Ford

I'm in for one too.

Sounds good, I’ll order the OEM part this weekend and work on reverse engineering unless someone jumps in first.

Is there a desirable filament for these from everyone so I can put together run times and material cost which I’ll share. Not looking to get rich, just get paid for my time.

I would use petg because that’s one that I have and I know it’s better than pla, but I’m not sure how it will hold up under the hood with the heat based on some quick googling.

This is an export from the database my additive manufacturing business uses. We never use PETG for high-heat applications, including under the hood. ASA is generally going to be the most cost-effective material to use in this application that still leaves an acceptable thermal resistance margin. We're at capacity but I'm sure someone here will get a solution put together soon.

Filament	Engine Compartment	Approx. Tg / heat limit*	Description
PLA	No	~55–60°C / 130–140°F	Glass transition far too low
PLA+ / Pro PLA	No	~55–65°C / 130–150°F	Still softens/creeps with heat
Silk PLA	No	~50–60°C / 120–140°F	PLA plus weaker additives
PETG	Limited	~75–85°C / 165–185°F	Can soften/creep in hot engine bay
PCTG	Limited–Good	~85–95°C / 185–205°F	Better than PETG, still temperature-limited
ABS	Yes	~100–105°C / 212–220°F	Good general engine-bay material
ASA	Yes	~95–105°C / 200–220°F	ABS-like heat resistance; very durable
HIPS	Limited	~90–100°C / 195–210°F	Heat okay, mechanical/chemical properties mediocre
Polycarbonate (PC)	Excellent	~140–150°C / 285–300°F	High heat strength; tough
PC blend	Yes	~110–140°C / 230–285°F	Easier printing; heat depends heavily on blend
PA6 Nylon	Excellent	complicated	Excellent mechanical/heat resistance; absorbs water
PA12 Nylon	Yes	complicated	Tough, chemical resistant; less stiff at heat
PA6-CF / Nylon-CF	Excellent	commonly 150°C+ HDT	Excellent stiffness and heat resistance
PA-GF / Nylon-GF	Excellent	commonly 140°C+ HDT	Strong, stiff, heat resistant
PC-CF	Excellent	commonly 140°C+ HDT	Excellent heat/stiffness; expensive
PETG-CF	Limited	~80°C-ish Tg	CF adds stiffness, not much heat resistance
ABS-CF	Yes	~100°C-ish Tg	Stiffer ABS; good for brackets
ASA-CF	Yes	~100°C-ish Tg	Excellent general-purpose engine-bay filament
Polypropylene (PP)	Depends	~100°C+ usable range	Excellent chemical resistance, but flexible/creeps

I’d be interested in one as well. I’ll keep an eye on this thread. Thanks!

Any of 3D printing people have an STL to share?

Not yet....working it now.

After a few iterations I think I have something workable. Kept it pretty simple. The bolt is temporary and would be replaced with a proper lynch pin. Let me know what y’all think!

Is this for the 23+MY?

Judging by your model year rig.

Yes this is test fit on a 24. I think it should fit previous years as well though. Need to find one to test fit it on.

 

[FunctionFirstDesign]

Did some super sophisticated testing (ran through the car wash). Seems to do the trick.

okay we need some high speed low drag engineer type to print up some and sell them to us. I cant I am programming my VCR.

Looks like others are on the ball with this, so I'm going to bow out. Can't wait to see finished products.

I encourage you to still try a design. It's always good to see different iterations!
