Introduction: 101 Useful, Practical, Functional 3d Prints!

About: I am currently at college at the University of North Georgia Gainesville campus. I am enrolled in the Computer Science Associate degree and plan to finish with the Bachelor's degree. I was previousl…

This is a compilation of 101 useful things that can be 3D printed!

I did not design any of these models and am taking no credit for any them, I searched for a very long time(over 8 hours!) and downloaded these pictures from the Internet. I thought that this would be acceptable because most of the compilations of 3d prints online are small and of not useful things.

    Hi, it would be very nice if you have included links to the STL files - but find this as a good inspiration anyways. Thanks!


    Tip 1 year ago

    There is an easy way to find the files (if they exist of course).
    1) open google
    2) typ image (it doesn't matter what you typ)
    3) press 'images'
    4) use splitscreen (you can find easy toturials for mac, windows...),
    5) drag the image into the search bar
    6) Now you have to click on links, images to find the file.
    Good luck!

    does that sax actualy work


    3 years ago

    While you could theoretically print nearly any solid shape (that's the whole point) Having a plastic wrench is basically useless, unless it's printed with some kind of super strength material that'll be as strong as cast iron or forged steel. A plastic screwdriver is equally completely unfit for the task. Screwdrivers are often tipped with hardend ends to prevent stripping during use. Some go as far are carbide tips for screwdrivers, a Plastic printed one wouldn't have anywhere near the strength to be practical for anything but the lightest uses. Same with plastic scissors.

    Same with anything holding heat. Like You can't Make an ABS Tea kettle and throw it on the stove, or any other type of plastic as they're all mostly insulators and would turn into quite the mess. Same with the spatula.

    This list is basically just a list of generic useful things. Scissors, Knives, cooking supplies are all probably terrible things to 3d print unless you're absolutely desperate. Event he guitar pick, unless you can customize the flex in your print a flat ABS pick would be pretty bad compared to most available picks.

    Plastic Screw Drivers have been around long before 3D printers. Plastic drivers are used in electronics, wnywhere static charge or a magnetized driver could ruin things. Also, nylon is a very strong "plastic" and there are plenty of 3D printers printing with nylon.

    About the printed wrenches and screwdriver: there are nuts, bolts, screws, etc made from soft materials like nylon, styrene, acrylic, and the like where an ABS or PETG tool is more than up to the task. Oxygen bottle wrenches are made of plastic, for example. As long as high torque isn't an issue, I see them as far from useless. Even if they are made of plastic, they'd be a far sight stronger than most of the tools that come with things that need assembly. Like iPhone repair kits. Plus they're non-conductive.

    unfortunately I do not have the .stl files as I stated on the beginning I found all of the pictures online through Google Image searches, I would advise searching for it either on Google/Bing or perhaps on thingiverse.com. Sorry I couldn't be more helpful.

    Too bad you have to click through 101 pages to see them all


    Reply 4 years ago

    No there's a way to see all in fewer than 100 clicks.

    Totally irrelevant, but anyone else ready for an epistocracy?
