I have been for the past few years. Not as a hobby unto itself, but to produce custom functional parts for projects and household things. It's been extremely useful.
I haven't gotten into it yet, but I've thought of buying a 3D printer if I had more room in the house. It still seems like a bit of a novelty to me though, and I'm not quite sure what I'd use one for.. I've heard you can 3D print replacement parts for things around the house though (such as hinges for cabinet doors, etc.).
I'll be getting a new glass plate, so I'll have to adjust the nozzle
I'm also getting an octaprint kit tomorrow, that should be fun the play with. (Could have set one up myself, but figured a pre-configured kit was easier and not that expens

If a spring-steel sheet is available for your printer, I'd recommend trying it. Makes it extremely easy to lift prints off of the bed once they're done. (This is standard with the i3.)
When you get the hang of it, let me know, perhaps you would be able to print me a nice housing for my kuman 7" Touch Screen :-)
Yes, that is part of my main reason for the OctoPi. Getting a little tired with having to pull out the SD card, put gcode on it and move back to the printer.

I'm in no way a designer, so I'm not sure how well that would work out. Would probably need an STL file made by someone for that screen.
I did find a $12 case on Amazon, when looking up the screen:
Personally I'd probably buy a case, especially since you can get one as low as $12. Looks a lot nicer than what I'd expect to come off a 3d printer, LOL. :)

1.. Medical... when they are full on printing replacement organs and skin for skin grafting... it's almost there.
2.. Home purchasing and food... For when you need a new spatula and you go on to bed bath and beyond and "purchase" the print routine for one and print your own. Or, need food and we all have some kind of organic edible crap and some machine with flavors all hooked up to the printer, and you call mcdonalds and "print up" a big mac, yum.

Hello Ernest,
I have a Shapeoko 2 from Inventables.com. I have had it for a couple of yea but I don't use it very much any longer. My other hobby includes vintage stereo systems, including reel to reel tape decks. I got one deck made by A and after 30 years, the aluminum cams inside that were responsible for playi recording, FF/RW (everything was manual back then) had started to disintegra I was able to recreate one that worked perfectly and shared it on thingiverse.com. About a year after I had shared it, I was contacted by a business in Montana USA that services and restores the reel to reel decks. Aparently Akai decks were pleagued with the issue of poor castings and the c (there were 4 in each deck) would just crumble after 2-3 decades of use.
Anyway, I was commisioned by them to create the complete set of cams which t a couple of weeks. Nobody makes them any longer and they were used in 15 different models. Collectors were starving for a new source for them. I am happy to share that I made perfect models and sold the rights to them to the folks that commisioned me. He's selling them for $75 a set (all four could in the palm of your hand). He's happy, I was very well compensated and the community is very pleased with them!

teeth, or completely disintegrating due to age or chemical composition of the plastics.

Glad to hear that you're getting back into vinyl!! There's that whole debate over what sounds better, digital music or analog but I'm not in
it for the absolute quality of the sound. I enjoy the entire process
of getting the record out of the sleeve, using an anti-static brush to clean the dust off, manually place the needle on the record and then
sit back and enjoy looking at the album art and reading whatever is on
the jacket.
I have a Sony HAP-S1, digital music player for music that I don't have
on tape or vinyl. It's like a giant MP3 player. It's nice, but I
don't feel any connection to the music like I do when I own the album, reel or cassette. All of the hipsters are really helping to revive
vinyl and I think that is awesome. You really see so much more NEW
music getting released on Vinyl again!

Yeah, I don't buy the "vinyl sounds better" argument, but I to see the charm handling and playing vinyl. That side is something that modern media can't capture and reproduce. And album art is definitely better on a 12" cover! :

Along the same lines, sort of, is that an old fashioned
vacuum-tube amplifier will usually sound better as compared to a
modern solid-state one, assuming decent enough speakers are used.

With something like 5% intermodulation distorton - something rarely talked about with analog media. To my ears, that muddies the audio a bit, especially when there's massed vocals or instruments. But my sensory processing is likely different to most.
A lot of people do say CDs sound "harsh". The cause of this, from what I've read, turned out to be the sharp cutoff above 20 kHz, due to the anti aliasing filters and relatively low sample rate. At one stage, a CD player was released, which deliberately allowed aliased audio above 20 kHz to bleed through, and apparently, people did find this one less harsh. Vinyl can reproduce ultrasonic frequencies well, especially with the right shaped stylus.

I agree. Most MP3's just don't sound as good. I have a few albums that are FLAC files (supposedly "lossless recordings") that are supposed to sound as good as the original master recording. But I'll stick with my records. :)

FLAC is lossless in that it doesn't remove any data during compression,
as opposed to a format like MP3.. And it's lossless compared to the original digital audio (i.e., WAV file or CD audio track) - All of the digital data is preserved in FLAC format. With MP3, some of the audio data (which many people are not likely to hear) is lost, which results
in a smaller file size, but it doesn't 100% match the original data.
I have a hard time believing that a lossless format such as FLAC can't sound as good as vinyl. The Nyquist sampling theorem says that if the sample rate is at least double the highest frequency in the audio, the recording can faithfully reproduce the original sound. Some people
have argued that the standard CD sample rate isn't enough for some recordings - but these days there are higher definition digital formats
(i.e., 24-bit 192khz recordings). Also, I'd think it might depend on
the device/hardware you're playing the music on. Record players and devices for playing FLAC/MP3s tend to have different hardware,
different speakers, etc., which may have an effect on the sound. Many
PCs and laptops use fairly inexpensive audio codecs/hardware, and might not have the best speakers, which can definitely reduce the sound
quality.

I don't remember what it's called, but all the "rubber" in everything we use today isn't rubber, it's man made. After so much time, it revers to it's original gooey state. There are products that you can buy that you spray on "rubber" to preserve and lengthen their life but I've never used them. I ha to replace a belt in an 8-track player recently and it was stuck on EVERYTHI in the deck and was so hard to clean. Once it gets on your skin, it's there for days!!

Moondog, what kind of music were you into back when your records were new? What did you pull out of storage? :-) I used to love Van Halen, AC/DC, Pat Benetar, Heart, etc. Now, at 51, I've added a good bit of folk music, some classical, and jazz. I'm close to owing all of the Steve Miller Band's records. Not counting all of the re-releases and live albums (I hate live albums).

Yes big difference. Guitar amps don't necessarily need to be "hi fi". The right amount and type of distortion can enhance the sound of a guitar. Valve/tube amps are particularly good at adding the right richness to guitar sounds.
... A power so great, it can only be used for Good or Evil!Most musicians choose an amplifier not for it's accurate sound reproduction, but for it's flawed design characteristics (harmonic distortion, uneven frequency response.) Same goes with vintage speakers. The only time a guitarist wants a clean amp and good speakers is when they produce their sound before the amp via effects boards or pedals,and want only amplification. How it was explained to me was vacuum tubes produce warm even harmonics, while transistors produce harsher odd harmonics. Some of this is aged information

I feel like I can hear the difference. Always did even back when cd's first came out. There are for sure better/higher quality formats now. But you get into streaming issues with the size differences. Satellite radio is one industry that streams low-quality. I don't know what format they use, but it sux.
I bet there's a higher tier service you can pay for that is lossless or at least better. But it seems like im listening to a 128k mp3 when i listen to Sirius. When i flip to a CD or FM it's like night and day difference.
So i canceled my subscription.
FLAC is an excellent format.
I won't rip songs to mp3 and I won't download music if its under 320kbps because like you said, you can notice it.
Funny, audiophiles seem to swear by analog. I do too.
There's a certain warmth, hum, ambience from recordings made pre-digital that give body to the songs you don't hear when you play their digital versions on the same equipment.
Tubes have a couple of differences to transistors in practical circuits. Firstly, for moderate power levels, tube power amplifiers are often "single ended", which has the second harmonic as its strongest harmonic. Transistorised amps, including MOSFETs are usually configured as a complementary pair, which tends to cancel out even harmonics. Not the best musicians, who want those even harmonics. Tube aplifiers also almost aways have transformer coupled outputs, which are another source of distortion (fo better or worse), due to their iron core. Modern (hi fi) amps are generally coupled to the speakers.
transistors, and CMOS JFETS have been observed behaving harmonically similar to vacumm tubes. Even among basic bulk components such as op amps there are folks who swear one vendor's version of the same chip sounds way better even though their specs are slightly different.
It also depends on the exact circuit design used.

his testing, so he asked a friend to figure out the wiring scheme. The "proprietary format" turned out the same pinout as a CAT 6 patch cable.

Yeah, there was a lot of dodgy stuff going on with cables. The truth, AFAIK as long as the impedance of the cable is low enough not to be significant, t cable should be audibly "transparent". Heavy enough elevtrical wire should the trick.

Well, the product is marketed for use by humans, so actual double blind listening tests makes the most sense.

Yes, I reckon they would easily sell them. Me? I have too much Scots in my ancestry. I'm prepared to spend money for quality, but I'd still pay $50-$1 for decent electrical cable (copper is still somewhat expensive) than wastin $500 on something of dubious benefit.
