Doh - yes I see that now!
Looks like good stuff though.

Well I like it. (Said Florence; hopefully).
It seems to bond well and be tough enough for the job. Printing wasn't an issue, but flexible filaments don't like to be hurried. Consequently one of those 90mm long hoses took 10 hours to print.

You need very constrained filament paths for flexibles, CHT nozzles help get the heat into them too, copper blocks to keep the temperatures stable help as well - the exhaust bushes I do for example:
Take about 45 minutes on my printer that's specialised for TPU, but 4 hours on my fairly standard P1S even though the motion system on that one is capable of 4x the speed.
You have to be very careful with TPE's for car parts though, a lot of TPE's have very modified behaviour and low melting temperatures vs TPU's to make them easier to print with them being softer (and some TPU's are really more like TPE's because there's a lot of overlap).
There aren't many TPU's that I trust for car parts and I've tested dozens.

I made a Nema17 bracket from Thingiverse.
I also designed a bracket to keep the cables from dropping onto the cross beam. I am not happy with it and a new design is printing

New design fitted and working. Really please with the result. The addition of a mesh has helped with smothing the travel.

Not been known to learn to walk before I try to run, I have been making TPU scrap on my new K1.
Trying to print a lens hood for my old Contax 18mm Distagon wide angle, I have had the predictable filament jams and failed prints, I have done the internet for fixes, what settings to use, cleaning out the extruder by taking it apart but it was not until I saw @ajlelectronics post that it dawned on me, its the filament getting stuck in the contorted path it has from factory. Step in the Benbo tripod filament path.
Basically having stuck a bit of filament in the filament run out sensor, off the roll up to the tripod and back down to the extruder, not what I had envisioned but for the few times I will be running TPU it is liveable with.
The results are not impressive where the supports were, it looks well pock marked but where there was no supports it looks good for a first attempt.
I have taken a couple of shots indoors and no vignetting so that is good.
As this is the widest angle lens I want to make lens hoods for I am calling it good enough to move on to those less extreme like a 25mm and a 35mm. I may well revisit this one when I have a bit more experience, I wonder if you can sand TPU I think I will experiment on some of the scrap.

Exactly those thought kept me away from it until I thought the market had matured a bit.Thats exactly what worries me about the printer rabbit hole, I just know I wont have the dedication for it
I console my self that the mental list of 'if only I had a 3D printer I could do XYZ' is an itch that is finally been scratched. It is a massive learning experience far from the Star Trek replicator

It is only that some of us won't take no for an answer! Some of us also like to find answers to "it won't do that sir". If you use the printer as designed, with standard filaments, then it will be quick, easy and reliable.

I will have a look for that, I have already made the skateboard bearing upgrade filament spool holder to replace the standard one which works well with the card spools but is a but too over running with the plastic spools.

Creality k1 top spool holder (with roller) by StoneGAS
To help extruder with super flexible TPU you need to get rid of the ptfe tube and place spool above printer, so it can easily extrude filament. so i combined some cool models and made this remix with roller. Now Such TPU as FD-Plast can be printed with speeds 30-60mm/s...

My new Elegoo 3d Max doing a great job as usual. Layer lines hardly noticeable.
Print is bigger than it looks. About a foot in diameter. Used 200g of filament at only 15% infill. Would make a great giant snow globe.

Printed straight off no problems. I used Elegoo PLA - I think it's the best one I have used. No stringing at all.

The village where the christmas elves living. by Harley
That´s the place where the elves from Santa Claus living. My doughter has Show me a Picture from a village in Comic style and has say to me, i want have such a village printed. So i have become my assignment. :-) I have draw it with 123D Design app on my Ipad. The Details are made in the way...

All the pictures show the plate is held on by six rivets. You might be able to find the holes or sheared off rivet shafts on your machine and obtain a measurement.
This one is a bit small, but could be scaled. Knock off the .txt at the end to change it back to .stl

A T5 gear (done on the Ender 3) for an inverse kinematics robot arm and the start of an RC boat - glued together four sections of hull. This was on the Ender 5. The inside is rough but I have now fixed the stringing issues I was having so the next version should be better.

Is that with a standard 0.4mm nozzle and how long a print time?
Yes standard nozzle. 0.2 layer height. 15% infill. Took about 36 hours and used 200g of filament. I really am totally delighted with this printer. Our first one was a Tevo Tornado and we pretty much gave up on 3d printing it never worked right. This Elegoo Neptune 3d max hasn't failed yet its awesome.
