  • Old hardware is awesome to reuse most of the time but it’s not nearly as efficient as our hardware today.

    It’s probably good to just properly recycle the old gear and spend $200 on a mini-PC from Amazon that has three times the power all while using less electricity.

    I usually completely tear down old equipment into is raw materials, the best I can. It’s less likely to be shipped off to another country for uncontrolled destruction and I get more money back for the materials.



  • OpenSCAD has its uses, but would hardly classify it as full CAD software. Prusa, I believe, used OpenSCAD for a while but they even moved to Fusion360. FreeCAD would be great if the devs would stop trying to reinvent the wheel in their UI. There is a ton of potential, but it simply isn’t where it needs to be yet.

    Fusion360 or SolidWorks are very well established in that space and their shitty license models reflect that.

    Still, as a free alternative, FreeCAD is where it’s at. You just really need to understand if it will suit all of your needs and for me, it doesn’t.




  • I will echo many others here: It’s going to be rough getting good deliveries. While you are planning on running a proxy, that is basically the same as running an open port where your server is. While it may seem to be a good idea to send email from a random AWS address, it really isn’t. Unless you are behind an IP that is specifically trusted as an email source, your traffic has a higher probability of getting dropped. (Many dynamic IP ranges for home internet connections are marked as invalid or untrusted sources, btw.)

    Additionally, email servers are a hot commodity, especially if they are not blocked (yet) by the larger filter providers. All it takes is one or two reports or a poorly configured firewall/IDS to auto-trigger a submission of your IP address as “bad”. By hot commodity, I mean you are going to get fuck tons of vulnerability scans. It’s not the end of the world, but it’s super annoying.

    If I was operating as a Jr. Security Analyst again and saw and sus traffic coming from your address, I would submit a block and not think twice about it. Hell, most of those types of blocks are automated anyway.

    However, if you do set one up and all is golden, great! It’s worth the experience but something I won’t ever do again. (Yes I did run my own email server before.)




  • Thank you.

    Isn’t it really cool that some of the best engineering projects leverage extreme simplicity? I am not saying that I am a grand architect or anything like that, but this simple project is a perfect example of why most people want to learn 3D printing.

    After thousands of dollars were spent on 3D printers, rolls of filament and replacement parts with hundreds of hours dedicated to learn about printers and CAD, it all just boiled down to being able to design and print a silly drywall anchor on a whim.

    Ain’t this hobby glorious? :)


  • Aww, thank you! I can be a sarcastic ass sometimes, but such is life. Regardless, it’s fun to design and share things. That reminds me… I included the .f3d file with this design but I forgot to add a .step. I’ll add that and some clearer dimensions for it tomorrow.

    Lemmy just needs all the love it can get and interactions are super critical for that. After being on Reddit for over 12 years, it’s great to be part of something new.


  • Thanks for comment!

    I tried a few anchors that were already out there all of them broke at the layer lines easily with PLA. Granted PETG would probably have mitigated that issue, but I didn’t want to change filaments.

    The toggle anchor would be fun to design, but designing a hinge that would work universally across many printers and filaments would be a challenge, for sure. Cheers!


  • It can, yes. However, it is only by 3mm. The print orientation is the way it is so that it can survive a hammer and some love taps. (I already tested that, btw.) Additionally, I wanted some extra meat on it for easy removal later and it may be hidden, depending on your application.

    In theory, you don’t need the support ring if the hole you drill in your drywall is a perfect fit. I have traditionally drilled my drywall holes a hair small for these kinds of mounts, so if you do that, not using the ring may work. Or not.




  • I think there should be an option (unless there is) for mods to turn off (or hide) voting as needed. That might be an effective way to cancel any downvote brigades. Lemmy really doesn’t have the population for mass vote manipulation now, but it will soon enough.

    Hiding all votes can also help mitigate some superficial bias, but not all. I believe that if a person sees a comment with a few dozen downvotes first, they tend not to read the post objectively. After being on Reddit for such a long time (12 years or so), I found that it was super easy to manipulate voting trends if I caught a post or comment at just the right time.

    Hiding only downvotes is just silly though. Some register of public opinion, positive or negative, still has its uses, IMHO.
