I personally think PETG would do the job but either way I hope you come right

With AI slowly taking over the world I recently had another look at the AI mesh generators. Previously the results were pretty bad with objects looking like a mushed together clay model done by a 3 year old. I was pleasantly surprised with how far things have come along.
Rodin is my current choice so I'll share a few screenshots showcasing it.
For the prompt I started small and who doesn't know the good old benchie tugboat so I thought its a good test for the AI to get started with. For my prompt I used simple text: "Make me a tugboat I can 3D print as a print quality test."
Rodin works slightly differently in that it first creates an image and not 3D models like most other tools so here's its first attempt:
Not bad right. So my curiosity got the better of me and I clicked the refresh button to see whats next:
Also pretty good so lets go ahead and see if the 3d model looks as good. A couple of minutes later I get my 3D model. I can change my prompt here and also click the redo to try again.
Once generated I can see my final object:
Importing the obj file gave some errors about the manifold but here it is in the slicer:
Slicing it:
Not too bad, lets try something more practical.
Next I tried to get a stand for a mobile phone: "Create a sleek and modern 3D-printable stand that can be used for a mobile phone."
That didn't go as well. I tried a few different prompts to try and remove the phone from the model without success. So far I find its pretty good at creating organic things like characters, dogs, cats and other models but not so great with practical things like phone stands, pen holders etc as its not able to separate the models and understand you dont need the phone or pens as part of the model.
All things being said things have moved along swiftly and compared to my testing earlier in the year I can see myself printing AI generated characters in the future.

Send me a download link to the file and Ill see how it comes out. The cold in GP isnt helping chamber temps at the moment. I have some black ASA around here somewhere.

That is looking great. Couldn't get it to work on my S1 so I will stick to petg from now on

I love this hobby.
Busy replacing some old transformer based MR16 downlights with GU10 ones and I want to move to plastic fittings and wasn't impressed what I found online and then I remembered I could just print my own. Found a ready-to-go model on Printables, and just had to tweak the dimensions for the right hole size (bless the uploader who provided an original project file).
The file if anyone is interested: https://www.printables.com/model/290508-gu10-socket-led-bulb-mountfitting
Printed this test piece in PLA, will print the actual ones in ABS. Will test fit things tomorrow, and make any adjustments I need to make. The PLA is too brittle (and bad with heat) and already snapped one of the clips off accidentally.

Nice!
Having printed items with similar clips as well its difficult to get them right, its all about the orientation which then makes this difficult to print

It’s the best thing about 3D printing- the ability to knock out practical items quickly.
It’s why, in spite of the fact that I don’t print much, I’m so tempted to upgrade to set and forget printer with an enclosure like the Carbon (so that can print using more robust material than PLA)
If you redraw that part / had a STEP file etc. you could cut those clips out and print on their side and glue in place, or add a fillet at the back to strengthen the base a bit more.

Yep, I made the clips a bit thicker and added a chamfered rim (I couldn't figure out how to get the cut profile to remove the chamfer piece in Fusion so just left it around the entire piece).
Printed another test piece with PETG and it's way better now and fit perfectly with no broken clips even after test fitting it a few times. Now printing a final print in ABS.

Carrying on with my light fitting project.
Printed in ABS but it was super brittle like the PLA, may have to rethink the clamping mechanism. Also I hate printing in ABS, my flat smells like crap for hours after printing with the stuff even with all the windows open.
I would just use PETG but I'm a bit concerned about the deformation temperature which seems to be around 65C. I measured how hot the bulbs get after about an hour and it was at 55C on the top surface of the bulb, that's not a lot of headroom. I wouldn't want the fittings getting soft and falling out of the ceiling.
Might grab some ASA if I can find any in white.
Maybe try print your abs hotter, has it got an enclosure.
You could try to push pull the 6x clamping sections and make them thicker by 0,5mm etc. Put 2mm fillets on the sides/base.

I was already printing it pretty hot (I think 260 - 270), it's just not as ductile as the PETG.
Out of curiousity I bought some nylon today as I was shopping for Shelly relays and found super cheap transparent nylon from DIY Electronics, so going to try it out for kicks.
Please show us your Nylon experiences. I've never tried it myself for various reasons and I've figured the effort wouldn't be worth it.
PC-ABS seems to offer much of the same kind of benefits, without the hassle.

Where'd you get the white ASA and how much it cost you?
