I have just about finished up with the parts on the 3-in Nuke Dukem. I printed the nose cone in PETG and it was a nail biter as it approached the tip, but it turned out real nice. Unfortunately, it's a little thin, but it will work for the interim. I am still putting the final touches on the retainer and centering rings. They have a great fit for both MMT and body tube, but I was having some issues with my slicer and they came out yucky (and now I'm out of PETG). I will post everything to Printables when they're ready.

I also worked on finishing up my Red Max Extreme scratch build. It has a 29mm MMT system that I designed (on Printables) and should do nicely on it's maiden. Hope to have it ready for paint tonight and ready to fly by week from Saturday.

Finally, I am currently printing a helping hands PCB clamp. I struggle when assembling the Eggtimer alts. and this should help at least keep things steady.

100% correct. If it prints well, I am interested if you consider sharing the design

I have posted the model for the Retainer on Printables:

Caveats: I don't have a 38mm motor case to test this with. I am currently using a 29/240 AT case with 38-29mm adaptor. The ring to keep the motor from pooping out the back fits fine as does everything else, so it should work with 38mm. I will be getting both 38 and 54mm cases this year, so that shouldn't be a problem.

I discovered a problem with my print profile when I switched over to Orcaslicer, so my prints didn't come out looking great but the threads are buttery and everything fits like a glove with LOC tubes. I think I will reprint them once I get more PETG tomorrow but I feel pretty confident with this design. I extend the offer to anyone to check the models out and feel free to to provide feedback.

@cwbullet, if these pass muster with you, you may add them to the STL repo

In other news, I finished the PCB vise for building Eggtimer kits. It's a really nice model. I will be building a few Eggtimer kits this year and look forward to using it.

I will test it.
 
I created and printed the all-in-one glider pod. This was about the 4th or 5th generation. Started out with much thinner walls on the main tube but those turned out to be a bit fragile.
It has built in launch lug and thrust ring. Small hole for attaching a kevlar thread shock cord on the front. Printed in PETG, total weight is 17g.

Now all I need to do is print and attach the hook to any new gliders and i can just re-use this pod as much as I need.

Looks nice. Have you tried it with PETG before? I had issues with the motor heat on some small BT-50 A/B class rockets. And ejection charge was actually worse with lots of distortion.

Are you happy with your XL? I just order another MK4 and will be ordering 2 more mid-March. I am thinking about getting an XL.

Yes. It is a well-designed machine. I have a 2 head but I thinking about upgrading to a 5 head.

The MMU3 appears to have fixed many of the issues of the prior version, but the MMU3 and AMS from Bambu still go through a single nozzle. The multi-head printer is a superior way to do it.

I had one print that failed due to a failed switch and 100s successful.

Good to know. I will probably get it with the 5 heads.

I would recommend the sumo enclosure over the Prusa version. $299 is a lot less than anything Prusa can.

I went with a photo tent as a low cost temporary XL enclosure, but the Sumo might be the long term solution for me as well. I might just skip over the MMU2 and MMU3 upgrade kits that are still in the box and go straight to the XL 5 tool upgrade. The MMU has seemed too finicky to invest the time to set it up and now it is looking like a dinosaur.IMG_9989.jpeg

I tried Prusa Connect in wifi mode and the uploads were slow as molasses. I found it a lot faster to just sneakernet the gcode file between laptop and printer with a thumb drive.

As for monitoring the print remotely, it’s kind cool but I can’t change filament, clean the bed, or remove the old print unless I am preent in person. The other residents of my house would be less than reliable in this effort.😎

Agree. Prusa Connect WiFi seems more like a gimmick. I didn’t bother to assign static IPs and it’s not worth the trouble to reconnect them. Ethernet is the way to go long term.
 
Not a rocket but related. Printed more wall art for the hobby room. This time it's an X-15 in NASA colors. These silhouette aircraft are fun and easy to print. They dress up any wall... I designed this in Fusion 360 off of 3-view I had in a book. The print is set up to work with the splash of color or just a simple black X-15. The SR-71 is done and a Space Shuttle is next. I'm still working on getting my wife to "OK" the B-52 for the hallway...next to the pictures of our children...

awesome. Are you converting down from an image or did you actually design that "manually"? If ur willing to share the file, I'd love to try it on my laser cutter
 
Still working on printing the Menace Intake for my 3-in upscale. Something is suddenly out of wack and the print fails between 40-90%. I think the print is shifting, but adhesion hasn't been an issue with this model until the last couple attempts -- I've been fine tuning the alignment so it lands perfect at the aft of the body tube.

This time will be a winner! What could go wrong?
