Is 3D printing worth it?

A few real-world workshop examples that make use of 3D-printing.
I hate how 3D printers are always advertised with the things they can make. Mostly figures or models of stuff that just looks cool in the first moment, but very few people actually need that.
That's why I didn't want to dive into 3D printing for some time. Since I then had access to the printer of my dad I came up with a few things that actually make good use of a printer for the workshop.
The materials I used were PLA and PETG. Everything that was white was PETG and the rest was PLA.
I use soldiworks for designing.

(not all parts of this video are on Thingiverse yet. Some still need some work and will be published in the future. Also when I make new parts, I'll add them to my account)

some of the filament used in this video I got from banggood:

Enjoy the video!

Please watch the whole video before writing a comment. Often questions you have are answered later in the video.

Sometimes you seem like a wise old guy whose been around precision workshops for decades, passing on your skills to the _youngsters_ in the audience. I'm 74 years old and enjoy being one of the _youngsters._ Those endless examples of your high quality design & 3D printing had me captivated.

You, young man have demonstrated beyond any shadow of doubt that you should be earning a very large salary ! I have enjoyed your videos for a long time and always learn something ... I'm 75 and have been 'technical' all of my life. I have several workshops at home and there are very few things I won't attempt. I don't have a 3D printer because I had doubts about the usefulness... you sold me, I am going to buy the same one you have ... you should be on commission ! Thank you, I know how long video making and editing takes. :)

This is, BY FAR, the most practical use for a 3D printer in a shop i have ever seen on youtube! You made so many cool and handy things! wow

'Aluminium. Because to some people pronouncing it correctly is more important than the content of the video.'

Thanks buddy. You made my day :)

This is the first 3D printing video I think I've ever seen that isn't just some dumb "Let's print this C+ Yoda model... Again! BUT WITH GLOW IN THE DARK PLA!", but rather shows how powerful a tool it can be if *you actually have something useful to print on it*

Incredible quality of work, super practical, very well presented.

I very rarely comment on YouTube videos but here I will make an exception. Firstly your spoken English is actually better than many English people I’ve heard speaking and English is their first and only language. It doesn’t matter if you use American pronunciation or British (although British is the correct way 😂) if people viewing your videos don’t like it, stuff them. Secondly for such a young person that doesn’t have decades of experience, I think you are close on genius. You clearly have a great mind along with numerous varied skills at your disposal. I am fast approaching 60 and I would be very happy just to have 10% of your skill level. I imagine your parents are extremely proud of you. Thank you for taking up your valuable time to share your knowledge.

Dude...you're a 3D printing monster. Some really great precision there, upholding the German way of making things. Cheers! Chris.

You had me at "skip the coil of a flexible hose".
Need to patten that one!

[BlueKinTsukiko]

I love how everything is with actual purpose. You opened my eyes tremendously when it came to just the expectations a 3d printer can do. Not just models but actually useful stuff

[jacobabylon]

The fact that you published the files says it all to me, thank you young genius !

I've watched a bunch of 3D printer videos, but this is the best one that actually shows the endless possibilities of printing useful objects. Excellent job Marius! You've got a great mind!

[belchnasty]

Some of these are pure genius! Btw i'm using this video of evidence to my wife that I need a 3D printer!

[ЛевКарманов-уш]

You're a perfectionist, I've never seen a master who is so meticulous in the organization of the workshop. Every your design is so elaborate.

[anchorbait]

That dust collection hose clamp is legit

[zannnewman]

This guy is a damn genius. Nice work man

Is 3D printing worth it?
Yes, you can make parts that don't exist and make replacement parts for existing equiptment.

[darrenmurray]

You are proof enough that the main limitation to 3D printing is your imagination.

I’ve only been tinkering with 3D printer for a few months, but I am in awe of the sort of work you’re doing in your workshop.

[JustinDepew]

My 3D printer is my favorite woodworking tool. You demonstrated excellent use of it. Your designs are well thought out and I can tell you've spent some time on them. We'll done!

[bobmiliano]

I HAVE DONE A LOT OF PRODUCT DEVELOPMENT WORK, AND MET TALENTED DESIGNERS, BUT, YOU ARE REALLY THE BEST I HAVE EVER SEEN ... THANK YOU FOR SHARING
