    This is my first prototype. It is hard to see in the picture but in your hand it is very visible. I am trying to make my own cover plates for my shop to show what voltage/amp but mostly what breaker it is. For some reason my main centre hole is not in the middle, i am going to have to go back to my model and see why.

    Very cool... I'm in the process of making my own vacuum hose adapters for the shop. I have 3 different ends that I have to remove/attach to the end of my small dust extraction depending on the tool I'm using, so I'm converting the tools to a common end.

    Using this as a starting point: https://www.thingiverse.com/thing:1246651

    One of my recent prints was a big road-salt salt shaker.

    Call me nuts, but I've had issues getting even distribution of road salt using the current "cup and fling" method I'm using... so I went looking and sure enough someone had designed an actual thing to do the job better.

    Seeing as I'm trying to figure out some of the details around printing ABS, I figured why not, give it a shot.

    This is the 3rd result after the first 2 got really screwy due to low temps, curling due to cooling, and no proper bed adhesion. After tweaking some settings and using a raft for a base, it came out pretty damn good overall.

    The lid was a separate print, and had the option of different sized holes depending on the grade of salt you use.

    Overall it's worked out awesome, especially since our constant freeze/thaw weather here has meant we're going through salt like a motherfucker.

    Never mind that TSC wanted $14 for a plastic scoop. Fuck that. $500 printer, $2 of ABS filament from Amazon, and 16 hours of print time is obviously superior.

    That is one thing that took me by surprise is how long prints take.

    I am getting better at using a cad program. Fusion 360 is great. Not designing anything particularly hard but it is fairly simple to use. My biggest weakness is one the CNC side of things, is one i get what i want modeled trying to get the cutting paths right.

    I've got the designs for guns from Defense Distributed if anyone wants them.

    Not touching that with a 10 foot pole. You can build a shotgun with about $20 in hardware store parts (plus YouTube and google) and rest assured that it’s not gonna blow your hand off. But setting off a high-pressure cartridge like a pistol or rifle round in something made of plastic is a recipe for killing yourself in short order.

    What if you add some duct tape?

    Honestly, a subsonic small calibre is pretty safe to fire more than a few times from the high-performance 3D filament. Or so I've heard.

    True. I imagine owning a .22 firearm I printed at home would be pretty cool. I’m not sure I have the computer skills necessary to really take advantage of 3D printing but I love what it’s doing in so many different areas, especially prosthesis. And seeing the printers become accessible to the average consumer, im sure my kids will look at one the way I do a copier.

    The lower being the part that the ATF considers a "firearm," for whatever reason.

    On an AR-style rifle, I'd be comfortable 3D printing anything but the buffer tube, bolt and housing, and chamber/barrel.

    And I'll be the first one to jump on a residential-version metal sintering 3D printer. Not necessarily for firearm purposes, but there's about a thousand different things I can think of for projects around the house and on the ranch.

    just got some wood PLA and wanted to test it out. Just did a speed run shit layer height and fast speed. That is a 20mm crate prop.

    The lower layer height with lower print speed, the detail turned out really nice.

    What printers do you guys have? I want to get one, but there too many choices. At this point, I would lean towards the cheaper end, but all recommendations are welcome.

    A 3in1, snapmaker, 3d/laser/cnc. It has a small bed, but there new kick starter is out due in about a week and some bigger one. I am really tempted to get another one.
