3D Printed DIY Turntable

[Doc B.]

That Atomic CF filament sounds like great stuff. Please keep us informed!

Way to make me jealous, now I want to order some of that filament and try it for the build.  The Prusament PETG filament that I did order got held up on getting shipped due to the holiday and people being out, so I won't get it until Wednesday.  Where did you order your filament from? I may just print off two copies with different filaments and try them out to see if I can hear a difference.

I think that filament could be cool for my car build as well.  I can think of three ugly aluminum brackets I poorly made for my build that could be improved on if I ever get a hang of Fusion 360.  They don't really need to be that strong but heat may be an issue for two.  I am probably just trying to cheat my way into saying I made a couple custom carbon fiber parts for my build.

I'm the one who is jealous, you have the kit!  I hope they get it back in stock soon.

The filament is from Atomic Filament

It is fairly easy to print with.  I print it at 260 and bed at 85

Have fun with the Turntable kit

Got everything printed off last week and put it together this weekend.  Pretty easy build outside of one step that takes magical powers.  Not sure how they expect anyone to accomplish the step which requires putting two tiny brass cups on the ends of a little spiked rod that pivots the arm.  You in theory put them on without them falling off while you piece two other 3D printed parts together around it.  No brass in mine and it still seems to move freely.  My clumbsy hands dropped one on the carpet, never to be seen again.  Still tried to put one side in but seems impossible for two human hands to me.  Everything else was simple and it probably took me 3 hours total to piece together after the 3D printing. 

I still need to do the calibration and dial it in, but that will come next weekend. 

As far as the 3D printing goes, everything seemed to print well on my Prusa MK3s+ that I built last year.  I used Prusament PETG in Ocean Blue and Gold.  They recommend printing at .3mm layer height.  I never normally print that big and just did .15mm layer height for everything.  I also did not find that I needed to use a brim for everything like the recommend in the instruction.  I'm not really sure how long it took for print time but I spread it out over about four days.  I would guess around 15 hours of print time. 

I'll report back next weekend after I calibrate it and add it into my living room system.  It will just be going to a Denon AV receiver for now, however, I might have some more projects coming there soon

Nice.  I hope it comes back in stock soon. I have printed the parts, and as you said nothing very difficult to print

[EricS]

That’s pretty cool looking, quite the minimalist design!

[debk]

The kit is back in stock, so I ordered one.  I have all the parts printed already.  Not expecting much, but it should be fun

Finished the 3d-Printed turntable.  I used red and black carbon fiber PETG.

Works well and doesn't sound bad.  Better than I expected!

Don't know if a higher quality cartridge would improve it much.

All in all, it was a fun project

[Doc B.]

That is pretty darned cool.

[EricS]

Pretty cool design.  Thanks for sharing your work, Deb!

It's a cute design exercise but I can't see it meeting the basic criteria of rigidity and very low resonance. A better platter might help, as long as you can get it centred properly. 3 bubble levels? which one do you use?

[Thermioniclife]

I would think you use all three. I wouldn't worry about the usefulness of the turntable and let the builder worry about that.

[debk]

You use all three by adjusting the three feet.  There is an aluminum part of the frame that gives some rigidity.  I didn't expect much from it and it was mostly a fun exercise.  It does work and sound better than I thought it would.  However, I have no intention of using it as my main turntable.  It was more a curiosity and a fun project.
