Winner! It did finally print successfully, but its probably needing some lube.
My printer is not slow on the load now. It was at first, but not now. Not sure what I changed.
Designed a AV Bay sled for my L3 attempt later this summer. After printing 2 prototypes one in PLA white and the other in metal infused PLA Green, finally printed the black PAHT-CF. Came out ok. Thru holes were a bit sketch with tolerances less than ideal. But, it looks cool.

Very nice.
Finally freed up the queue to print the Super Mario bros 2 Rocket.
First one turned out ok, but I was so excited, I forgot supports. It will still fly or with some clean-up make a nice desk ornament at work. The next one's gonna be a winner! What could go wrong?

The 2nd print of the Super Mario Bros 2 rocket turned out so great, that my wife stole it and claimed it as hers. I was hesitant to put supports on it b/c I've had trouble getting them off clean. I watched a YT vid by Maker Muse and anther by Uncle Jesse. Made some tweaks and the 2nd print was perfect. The tree supports basically fell off (with encouragement) and left no sign that they were there.
Today, I'm working on a printed retainer for my 3-in Punisher. Doing some mockups to see if my Menace retainer will work. I'm not above biting the bullet on buying an aeropak but I think I can make this work.

I've been using 3D printed retainers for years now. I have mostly 29mm rockets and all but the very oldest ones I've put PETG retainers on them.
They work fine. Haven't had any trouble with them. Yours looks like you intend to screw them to the centering ring?
I just epoxy the thread onto the motor tube. No problems ever. They've held up well over many flights.
@Alan R , I started making parts with my first 3D Printer last March and love building rockets with it. I have dozens of retainers in PLA+ (very similar to the model you show) and I have only had one issue, due to a design flaw. I recently upgraded my printer (Ender3 V2 Neo) with a Sprite Pro extruder and put Klipper on it, so PETG is a no-brainer now. I love PETG for building rockets.
You are correct that there is no problem with a simple glue on ring. The design here was intended so that I could pull the retaining ring off and replace, but the technical need for that is minimal. I have a simple ring variation that will do fine.
I am at a point now where I'm designing more models vs. downloading and I'm very much enjoying the process.

I am really liking PET-CF these days especially for the aft end
This has been the direction I have been wanting to go. What has been your experience with CF, what are you printing, and printing it on?

Printed a BT50 tube cutting guide with some "Aceaddity" brand PETG that prints awesome.

1515 rail guide was for 1/4 bolt, but needed to use it with a #10 bolt (which is more standard from rail-buttons, etc.). So printed out a small shim out of PETCF... works like a charm

Had some time while waiting on approval on some changes to the shrouds I am doing. So I got a couple trans and hojo nose cones printed.
I've been working on tackling printing nose cones on my printer which are too big. Cutting them in the slicer is easy but joining them afterwards, the results were less than stellar, as I'm sure many are cringing right now. So, I tried a threaded approach with the tip and base, and I was successful with that, and its solid but a lot of work to get it right and it adds a lot of weight. The other day, I realized that my SBR Fusion had the answer with a lipped, half-lap sorta joint. Wanting to see if I could replicate that, I took to Fusion360. This was the proof of concept design:
3-in Ogive Nosecone with Ebay R3V10
And Here is the result:
Printed 3-in Nosecone with Ebay Separated Printed 3-in Nosecone With Ebay Joined
Pictured with my Eggtimer Quantum secured with high tech, space-rated security restraints.
Checking the fit for my Menace 3-in upscale, it fits like a glove. There is just enough room in the lip joint between tip and base for a film of epoxy, then I will laminate the inside with a film of eeeepoxy as well. If the print breaks, it will probably be somewhere besides the joint seam when all is done.
I also printed the Gemini Joe Mini model by Jamie Claye found on Printables. It's a cool little model for my 11yr old to fly (after I'm done with it). I had too much heat and also under extrusions in places but its still functional and my son loves it (not as much as Minecraft, though).

That is very similar to how I tackle printing larger nose cones than my print volume.

Same
With my recent nosecone design fetish, I included a redesign of the IPL nosecone ebay. I used the IPL (scaled from 4" all the way down for use in my Estes Black Brant) for several rockets, having heavily modified it to my needs.
For this exercise, I set out to build it from the ground up, having the sled work with both my new nose cones and backwards compatible. Same for the nose cones. I want to have a sled that I can put in several nose cones, so I can have a simple Eggtimer quantum or quasar and swap them between rockets. I have simple screw-in plugs if I don't need electronics or just to keep the nosecone tethered.
The concept is the same as the original, with vent/wire access holes in the base for pyro charges. I added access slats to through the sled for wire management. I don't use the captive nut on the screw eye, so that went away. At the top, I have a threaded 1/4-20 hole for a rod to extent to the tip of the nosecone where I can attach nose weight. I successfully used this and the nose weight system with my Mega Red Max back in October. The hex holes are for the nylon standoffs and its sized for an Eggtimer Quantum.

Printed a thread insert holder and a new filament guide that uses bearings.
I love that color! What brand/type is it?
I printed a Skull phone stand for a co-worker.
