I drew up the F3 ladder in Fusion360. Here’s the STL file, in case anyone needs it: https://www.thingiverse.com/thing:2761619

Are there flexible plastics that these can be printed in? These are the parts that I periodically collect along the right of way, along with the hose assemblies!

Flexible enough for this, I think. I haven’t tried printing one yet, as I have another print job and running at the moment. Will report back.

Yeah, they need to be made of springy stuff, so they do not break when they get hit. Most stuff I have seen is stiff.

Greg

This stuff would make them totally flexible. The question would be whether they would stay in the engine. I guess you could tack them in with glue. https://ninjatek.com/products/filaments/ninjaflex/

you could add a bar between the “hooks” to act like a spring and keep the ladder secure. start thin and make thicker (taller in z axis) if more stiffness is needed.

I think I’ll order some of that stuff. I’ve been interested in trying it out.

check out flexfill 98A looks a little stiffer but still will flex.

Eric, the Ninjaflex filament, although a little pricey, is good stuff. Its quite flexible and relatively easy to print. I found it has good adhesion to the print bed which is a big hurdle as I am sure you have discovered. BTW: I have the Prusa i3 MK2s.

Thanks, Dan. I have the same printer, as you may know. I will try it out.

Eric,

You might also take a look at the brake cylinders. On the F3 sideframes they are in the wrong location

Wow! Thanks for trying it out.

Dan’s video shows on my Apple phone (Safari) but not on my PC (firefox) …interesting

Either way very cool !

All I have is Firefox on a PC, don’t own a phone, and likewise have no videos visible in this thread.

Edit; is also a no show in Google Chrome and Microsoft Edge.

For those of you who cannot view the embedded video here’s a direct link to the video on YouTube. https://youtu.be/B2BCEx0bry4

Don’t understand to difference in code …nor do I care …good stuff

Funny, video did not show at first… then when I clicked the link to see it, and then returned to the thread, there it is… weird.

In any case, thanks Dan for trying it, looks like a good idea considering how often these things get knocked off. Now to be sure to use flexible paint for them, like vinyl paint.
