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

Picture of 101 Useful, Practical, Functional 3d Prints!

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

Disclosure/Disclaimer:
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.

Note: I do not have the files to print any of the following objects, this is simply to give you an idea of the usefulness of a 3D printer. But, all of the images were downloaded from the Internet and if you search you will probably find the file to download if you would like.

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.

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.

The GamingC3 (author)2017-03-07

Can I have the .stl file for the d20?

Or any kind of file for the d20? I can convert it using autodesk.

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.

FilipN13 (author)2017-01-29

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

WillW70 (author)FilipN132017-03-07

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

Totally irrelevant, but anyone else ready for an epistocracy?

JavaProgrammer (author)WillW702017-03-07

click view all steps and you can see them all in 1 click.

OwenM45 (author)FilipN132017-02-05

There's always one

DavidK369 (author)FilipN132017-02-03

Step 1: Click "View all steps"
Step 2: Don't click through all 102~ pages

Step 4: Profit!

All the negative people need to put their egos aside and play nice. You can be helpful and not be a jerk.

cart562 (author)2015-05-27

The picture for #51 does not appear to be 3D printed. While I'm sure you can print clips like that, the picture is not proper.

JavaProgrammer (author)cart5622015-05-27

Thank you for trying to help, but according to its source it is 3d printed.

You can clearly see the marks where the plastic was injected into the mold. Definitely not 3D printed.

Ok sorry, from the source I thought that it would be, my bad. It could still be 3d printed however.

Not with a standard extruding printer like 99.9% of use have. The overhangs on the female side of the buckle would be an absolute nightmare and most likely impossible.

print it standing upright?

You'd be able to most likely print the majority of it, but the actual slot where you thread your fabric or whatever would be near impossible. That's on FDM machines (standard consumer 3D printers, what about 99% of them are) but on sintering machines you would be able to do that no problem. Problem is they are still somewhat rare because of their multi-thousand dollar cost.

rhofstad (author)SoLongSidekick2015-07-14

yeah yeah.... people without 3D printers continue to appear as experts and assume stuff around on the internet I see :-) :p

Get yourself a printer and start experiencing in stead ;-)

It is SO possible to print those buckles on a FFF 3d-printer.

The best result I got was when i printed the http://www.thingiverse.com/thing:348729/#files and it turned out very nice, strong and smooth.

I printed 2 and I had to give one of them away first time i showed it to anyone. He immediately asked "can i have it?" when he got it in his hand :D

SoLongSidekick (author)rhofstad2017-01-09

Awww that's cute, I built both my printers. I'd love to see just how long those buckles worked for. got any pictures of them after actually using them instead of sitting on a trinkets shelf?

zzztt (author)SoLongSidekick2017-01-21

they are probably good for safety harnesses

degrooty (author)rhofstad2017-01-08

Get REKT @solongsidekick

SoLongSidekick (author)degrooty2017-01-09

I don't think you know what that non-word means.

99.9% of USE?

SoLongSidekick (author)Irishmun2015-07-10

Ugh thanks, supposed to be "us".

Marklc (author)2016-08-30

this is a nice reference for things in 3d printing .. but it is NOT an instructable .

The Knex Inventor (author)2016-07-26

Very nice guide! I have always been interested in 3-D printing; will have to try some of these out sometime.

JulianF22 (author)2016-05-03

Very nice, download links would have been even better!

I can't Find the Pencil stl file :(

Awesome ideas! I will definetly print a few of these if I ever buy a 3D printer

Kardolf (author)2015-11-12

It's really unfortunate that there is not an single instruction in this entire page. Even on Pintrest I can usually click on the picture to get to the actual items or instructions.

pavelpov (author)2015-08-30

Maybe i am thumb, but where can i find the stl files?

Chris Datuin (author)2015-05-24

Cool chess pieces, can you teach me how to do some simple 3D prints?

ivver (author)Chris Datuin2015-05-28

Google sketch up or Solidworks, google it , youtube is full of tutorials :)

Tater Zoid (author)Chris Datuin2015-05-27

He didn't make any of these.

I didn't say I did, in fact, I said that I didn't.

look in the "You might also like" section of this instructable and read the one called "My very first 3d print". it goes over the learning process of designing and printing something.

gdoc aka (author)2015-05-24

which application I for make better 3d design

ivver (author)gdoc aka 2015-05-28

Solidworks :)

JavaProgrammer (author)gdoc aka 2015-05-24

I have only used Google Sketchup but it seems to work very well.

ShakeTheFuture (author)2015-05-24

Great printouts.

Makes me want to own a 3d printer.

That's for sure.

nqtronix (author)2015-05-24

You Sir might possible earn the award for the 'ible with most steps. I'm impressed. I knew that 3D printers have a lot of potential, but I was never creative enough to imagine most of these prints.

JavaProgrammer (author)nqtronix2015-05-24

Thank you very much!

Lopany (author)2015-05-24

Thank you , there is some great ideas and again thanks for sharing

susiefreckleface (author)2015-05-24

great ideas and reminders. now I have an alternative over webcrawling to find a replacement feed-dog lever to my discontinued blind hemmer sewing machine.

Chris Datuin (author)2015-05-24

Cool chess pieces, can you teach me how to do some simple 3D prints?

I don't know a whole bunch about how to do 3d printing, I would suggest searching on the Internet and Youtube.com, maybe design some stuff with Google Sketchup(Free!) and then have in printed via an online service.
