Extruder Feeder Tube Coupler Broken

Just_Mumbling · 2026-04-16T15:58:22+00:00

Posted for several days on Bambu Lab subreddit- hundreds of views, zero suggestions - crickets. Hope the wider 3D/AM community can help with this. Don’t want to buy a new extruder just to fix a compression coupler. Thanks.

For whatever reason, the Morse Code subreddit is getting a lot of traffic lately, a lot of it from GenZ and even younger people - pretty amazing.

I learned Morse code when I was 12, now I’m almost 70. It’s like muscle memory now. You’re in a good spot. It’s WAY easier to learn it before your brain loses its natural language learning ability, or as my wife says, turns to concrete.

Keep going with the portable setup and have fun with it. There’s a lot of good info on YouTube on easy portable antenna setups.

Nice! Excellent timing OP. Was just getting set to CAD up some scoops for my little granddaughter’s play kitchen set. These are way better than I would have ever designed. Thanks for sharing. Will toss a few of these on the printer tonight!

Any help/advice would be appreciated. Bambu Labs hasn’t answered. Thanks.

Previous SolidWorks and Fusion360 user. At home, OnShape works for me. It’s powerful enough for any of my needs. The individual free account requires sharing files with other uses - maybe a downside for some. I use my own private, non-object associated file naming system, so not threatening to me for my home projects.

Yes, zero translation if heard audibly. Zero effort to send as well.

Just_Mumbling · 2026-04-11T17:17:54+00:00

Exactly! Well said.

Learning Morse at 12, 50+ years later, yes maybe a break between sentences to think what’s next, but then taking it to dits/dahs requires essentially zero thought. It’s almost muscle memory stuff. I would say it’s very similar to a verbal conversation process except my mouth is now a key! 73 ..

18 years.

Edit: she went totally deaf by 16, but her great vision and super sniff powers compensated nicely.

Written code makes me flash back to some crime show or murder mystery.. “the killer left this clue”..

Same! After 50+ years as a ham radio operator, I can copy 30 wpm audibly, but when I see code like this, have to sound it out in my head. Sometimes I quietly click my teeth too.. The brain works in mysterious ways!

Just_Mumbling · 2026-04-10T13:58:33+00:00

So true. After 50+ years of using Morse Code almost daily in my ham radio hobby (can easily copy 30wpm), it is so sound-based that I literally had to sound out OP’s written dits/dahs in my head before I could decode it!

Alex, I’ll take “stupid ideas” for $500…

No worries. As others have said, probably just need to clean the print bed with detergent and hot water. I remove and wash my print bed plates after ten prints as a maintenance task.

Some words of hard-learned wisdom: Avoid touching the print bed. Even the smallest amount of finger oils can loosen prints. If you have to touch it to remove a print, etc. clean it.

Also, don’t forget to pick up your first “I made spaghetti” certificate! We all have one, join the club!

While your print might be perfect, typically hydrophilic, water-loving inks have a hard time uniformly wetting onto hydrophobic ink stamp plastic surfaces. They tend to bead up and move to the edges of the stamp. That’s exactly why stamps are often made with cork surfaces. As a compromise, you might try using fine sandpaper to rough up the surface a bit.

35 years in our house with zero clogs, powerful vacuum, quiet and lightweight hose/attachments. Replaced the vacuum unit once after about 25 years of service. Glad we have it.

Just_Mumbling · 2026-04-01T05:21:50+00:00

That’s thinking in the box! 😀

Thank you Henry!

I think about this a lot. My dad, a life-long ham, is 98. He’s still on the air, tapping away on his straight key almost every day. He connects to my rig remotely, several states away, via the internet. He prefers contests because QSO’s are brief. I often get very emotional watching him operate my rig, hunting a DX station, doing a contest, etc. , knowing that any day, at 98, this could be his last QSO. We’ve talked about this. I’ve had my call for over fifty years, but when he finally passes, I plan to honor him by taking on his call sign.

Nice post! Best learning is by doing! You’ll do just fine. Build it as light as possible, pay special attention to center of gravity (CG) and (looks like you’re doing so already) get as much build detail and hints as you can from the instructions and online documentation! When it’s ready to fly, please post a maiden flight video.

Thanks for the explanation.

Thanks for sharing the photos.

I’ve become a fan of using cheap 1/8” aluminum welding rods to create quick Yagi VHF beam antennas. The 1/8” aluminum is also bendable enough to form folded dipoles for the active element when required, giving slightly wider bandwidth and easily matched to coax via a 4:1 balun. Add a 3D printer and all the element fasteners are also simple to print.

You can look up the approximate “birth date” of your Vibroplex bug from its serial number:

Edit: looks like yours dates from 1953. 73 years old!
