  • I have the same hyper sense of justice and so does my kid. Even knowing what is going on and understanding what they are dealing with, it is insanely difficult to try to get my kid to understand how to walk the fine line between being a good human/citizen and being a danger to themselves and society.

    It’s really amusing sometimes to catch people’s reactions as you explain to a child that sometimes lies are the right choice. That the truth is sometimes not only needlessly cruel, but also unjust and unfair.


  • FreeCAD is a great program for people who know cad. But it’s an awful place to start learning. I know first hand because that is what I tried to do too.

    FreeCAD has 2 major issues.
    The first is stability. As long as you do stuff the “right way”, it’s pretty stable, but FreeCAD is really powerful and has at least 5 different ways you can do anything, and as a beginner you will constantly find yourself going down rabbit holes that only lead to doom.
    The second big issue is documentation. It suffers from both too much documentation and not enough at the same time. The program has seen a massive amount of development over the last several years. When you search for how to do something you will often find a dozen instructions and videos on how to do something, but they will all be for older versions of the program. However, due to the fast pace of developments and improvements to the program there will be nothing about how to do something in the program as a current stands and it will be just different enough that the old instructions don’t work anymore. I do strongly recommend that you download and install FreeCAD. There will definitely end up being things that you will want to try that can only be done in FreeCAD, but you really don’t want to start learning the basics there.

    The other thing to know is that designing an object is only your first step. You then have to slice it and print it. Unfortunately, there is a fair amount to learn there too. Wall thickness, nozzle sizes, support structure, material strengths, ect. are going to require some learning of their own, so throwing FreeCAD on top of that is just cruel.

    I strongly recommend starting with something insanely basic like tinkercad. It will limit what you can create to a certain extent, but you will be able to quickly produce some models that are not complete garbage, that won’t cause the slicer to commit seppuku, and that might actually print without causing your printer to shit itself, and have some success with right away.
    Once you hit the limits of tinkercad you can then begin trying out the different CAD programs to see what makes the most sense to you. OnShape was the next step for me, but you should really just give them all a try to see what works for you.
    Also, as a beginner, the online nature of many programs is actually a big advantage. Being able to switch from my work computer to my home computer instantly has been really nice. I even use the OnShape app on my phone occasionally. You’re not going to be doing any kind of complex development on the app, but it’s cool to be able to pull it up and do some basic stuff while you are stuck in a doctor’s office or at your in-laws for the holidays.
    Plus, your initial designs are going to be hot garbage anyways, so it’s not like you have to worry about somebody stealing your ideas just because the free version makes your projects public.

    When I got my first 3D printer I had tons of ideas that I wanted to turn into 3D prints. But it took me months to even get to the point where I could print out things of my own design that weren’t garbage.

    I find that aluminum is the best medium for trial and error because even though it is somewhat expensive, it’s easy on the bits. And that is important regardless of the bulk material costs.

    Dude your CNC sessions are totally out of hand if you are having to buying aluminum in bulk. Just get yourself some shibari ropes and a blind fold if you want to take your time and make it an extended session.


  • Ya, we used to have more of the little fat slow white ones (orb weavers I think) around when I was a kid, and other than cobwebs all over the place, they never gave us trouble. I generally try not to mess with them though, or I’ll do a catch and release. But between the Brown Recluse bite I got as a teenager that took almost an entire year to heal and the other non-poisionous bites I have gotten while asleep or watching tv that take 6 weeks to heal, it’s insta-death if any others are found inside my house.
    I just realized that I am a spider racist. White and yellow get the gentle touch, but black and brown are going down.

    Not all spiders are buddies who will just keep to their website and kill pests. Many are aggressive roaming hunters that just go around biting shit to see if it is edible. And that includes you just sleep or sitting still.
    Also, even the nonvenomous spiders have some seriously bad oral hygiene and carry bacteria that causes deep infectious wounds that take months to heal.
    Even with all that, if they were just slow or stupid I might take the time to catch and release, but given that the majority are stupid fast, and/or actively trying to leap at me… they gotta die.
    Having said that I don’t fuck with them outside, especially the banana spiders, because banana spiders are instantly easy to identify and aren’t interested in starting trouble.




  • I fully understand that feeling. Of course there’s nothing that says you won’t be able to start it up again at a later date. 3d printing is seeing a seismic shift right now with cheap and reliable multi-tool systems showing up, by the time the economy recovers, efficient, fast, multi-color, and multi-filament will be the norm. And with some of the more industrial plastics and even metals available through specialty printing services, I think we were already going to see a bloodbath amongst the smaller printing services out there no matter what. So maybe right now isn’t the worst time to dip out of the market anyway. I would suggest that you take this time to hone your design skills or focus on the more niche aspects of the market. You got the opportunity to learn and sample the market while money was gushing into it market, but it was a bubble that was never going to last. So, now you have the choice to take what you have learned and find something sustainable, or just run the other way and do something different.

    I can personally tell you that having the market you are in ever so slowly shrink and die under you while you try to squeeze just a bit more out of its husk all the while feeling trapped because you have employees and customers depending on you… it’s fucking brutal. My family and I are doing well these days, but I can only imagine how much better I would have been doing if I had just called it quits much earlier.


  • Everyone is bracing for the economic free fall that is going to be the next 5 years. We are still at the upper end and it’s only going to get worse under this administration.
    So, I have no doubt that people just aren’t spending money on the kinds of things that they were even just last year. I wish I had something better to tell you, but it is going to be a while before we see people having the money to spend on custom designing anything. As the previous poster pointed out, you need to either decide to get rid of stuff and then sell it like you want it gone, or accept that now it is just a hobby that basically paid for itself.
