  • 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.







  • That sucks.
    Is your cpap a unit like the resmed where the water tank can be removed and not used? The reason I ask is because I am curious if you can hook it up without the water tank and let it run for longer than 10 minutes without you wearing it and then check to see if you still smell the burnt plastic? That would at least let you narrow it down to whether it’s a water tank issue or something in the head unit.


  • Take it apart and wash everything. They are really pretty simple devices. I literally just finished replacing the motor on my ResMed S9. It has 8 allen head screws in total, and they were all the same size. I used an allen wrench that came with my 3D printer, it’s not marked but measures 2 mm across. It took me less than 10 minutes to get it apart. This guy has a pretty nice breakdown.

    Everything except for the main board, SD card, and motor can be washed with dish soap in your sink.

    I’ve taken apart a couple others and they were pretty simple too, so I willing to bet that you can find a tear down video on pretty much all of them out there.

    Make sure to wash the water tank really well and wipe it’s inside down. Mini cpaps coat there water tanks with a bittering agent that stinks when you run out of water. So just be sure and never to let it run out of water, or turn off your water function.




  • That’s ok, it will still come out wrong because of some issue that you never thought of.

    This is why people share their models so freely online. It’s not pride in what they’ve accomplished. It’s because they’ve just spent 3 weeks and $60 in plastic to finally “correctly” print something that cost the original manufacturer $0.15 to print and would have worked perfectly if they had just stopped cutting corners when they got to $0.17, but saving that extra $0.02 per item made sure that it was definitely going to fail.
    And by sharing it you pass the curse onto others and enable yourself to finally produce a print that is still totally fucked but just good enough that you are willing to call it done and start the cycle over with something else.



  • For us older folk, and unfortunately, also for some younger folk that grew up in more “conservative” small towns, borrowing and fancy math trickery was the work of the devil.
    We were required to memorize the addition tables as well as the multiplication tables. And even then, addition could be done on your fingers and toes so as long as you could add the big numbers like 8 & 7 together faster than the really slow kid could take off his shoes and work it the hard way, you were considered proficient at addition.
    So ya, there’s a wide swath of America that just sucks at basic math.
