Emergency Exit Rear Door Release Ideas

[CyberGlow]

So my friend @That Beast Mode printed these from the 3d file and his came out very fragile for some reason. That’s why I was asking about the PETG

They were probably PLA is my guess

PETG is what I've been doing and even in below freezing they look to be good. PLA version was bendy in warmer weather, not sure what it does in cold. I've been meaning to try PC, but need to vent my basement for printing in that.

TickTock’s design we use with attribution

If I had a multicolor printer I could do colors like you and what his design has. I just started adding little plates with multicolor that glue on.

yes I’m not touching ABS or ASA until I have a solid exhaust system

What printer are you using?

Ender 3 V3 plus.

I have done ABS, but it was in the summer and put the printer in my shed. It works, but really need an enclosed printer to keep the temperature constant.

No, I printed them in Petg, it is a design flaw where the layers on the release handle are perpendicular to the force you apply. It is very fragile in that area - not to breaking but layer separation where it falls apart. Under an emergency situation, last thing you need is the lever snapping off. I'm at work now, but I'll take a pic when im home to illustrate what I'm talking about.

Ahhh ok yea if you can I’d love to see it

Will do, I still have the broken ones at home, I didn't throw them out yet (I think).

If you want to and if you can, send a pic of the actual pull handle from the side, I can show you where it

So the flaw is at this layer where it meets the handle - I took the pic off your site just to illustrate it for you, I'm in no way implying yours have the same flaw. However, I suspect the original designer knew it was a weak point as they put a hole for an M3 screw, but even with that, it would need some form of internal nut in the main body of the handle to not come apart.

Gonna take a good look when I get home tonight

Could it be due to layer height and infill? I'm printing at .20 and 15% infill and it is very strong.

That could be it

That could be it

Maybe bump up the infill

With 15% infill and I manually set the seam to be at the thickest part of the handle:

As a complete 3d printing rookie, this is a hell of a fun thread to watch. Got my popcorn out.
