When it comes to 3D printers and 3D printing, the following questions usually arise:
Where is free download 3d model for printing?
Why do they use 3D printing at all , what can be useful and interesting to do with it?
With what programs, preferably free, you can create a 3D model ?
These questions can be answered using the service directory of 3D models - Thingiverse . ')
In this post we will do a small review of 3D models from Thingiverse (grouped by the programs with the help of which they were created). As an example, the header provides a designer from 3D printed parts, created using 123D Design . More details about this constructor, and other examples of 3D models from Sketchup , OpenSCAD , Blender3d , FreeCAD - under the cut. In the beginning, a little about the service itself, and the specifics associated with 3D printing.
Thingiverse is a free service opened in 2008, developed and maintained by MakerBot (which in turn creates and sells a well-known 3D printer), anyone can register on this service and upload a 3d model for downloading. A key feature of the service is that all downloaded models are published under the Creative Commons license , which means that you can freely and freely download and also freely change.
The generally accepted format for 3D printing is STL (short for STereoLithography), this format contains only the shape of an object, without color, texture information, in fact it is a surface composed of triangles. It is in this format that you need to export 3D models if you plan to print them on a 3D printer.
We proceed to the review of 3D programs.
123D Design
AutoDesk is seriously entering the 3D printing market - it provides a good service for preparing 3D models, in particular, you can download the free 123D Design program. Available for PC and Mac.
Pixil Bits Constructor
3D printed designer Pixil Bits consists of several elements, on the basis of which you can collect a variety of shapes:

All files can be downloaded here , also provided the source code for changes in 123D Designer.
Birds mobile
Want to make sitting and spinning birds? (a good example for the basics of mathematics :))
The build process and the final result can be viewed here .
Here's what you need to print:

And of course, different layout options are possible:

The original 123D Design files can be downloaded from the project page .
Sketchup3d
Perhaps one of the most famous programs will be Sketchup3d , originally it was developed under the wing of Google, but later the search giant transferred this program to Trimpble.
Pros - a convenient interface for work, there is scripting on Ruby. Cons - not open-source version for Windows and Mac only.
Mini sumo robot
3D printed platform for a mini-sumo robot, contains a frame and a ladle blade.
Assembly process
Files for 3D printing, and original Sketchup files can be downloaded here .
All the details of the mechanism can be downloaded here , and here is the link to the archive with all OpenSCAD original files.
Gears
If you need to print a variety of gears, then you can see this project: Public Domain Involute Parameterized Gears , which contains OpenSCAD files for creating 3D models of various gears.
Blender
Blender3d is a free open source software for 3D modeling (supports Python scripting)
The author, who created the model - specially optimized it for 3D printing - there is no need for “support” support elements, the whole model is printed as it is.
Master Yoda
The quite popular model Yoda Figure was created using Blender, or rather “assembled” from several models.
On the basis of information from the original article , for its “preparation” were taken:
FreeCAD is a less well-known program, but rather interesting as it is positioned as a professional CAD system, completely free and open-source. Full Python scripting is supported.
Bike phone holder
Do you want to fix the smartphone on the handlebars? Then watch this project: Bike phone holder . Files for FreeCAD included.
From a different angle
Drawer handle
Need a box handle? No problem, the project Simple Drawer Knob . The original FreeCAD file is included in the download.
Want to make a hearth for your smartphone? The Parametric Acoustic Horns project will allow using the python program to generate the mountains you need in FreeCad.
You can hear the difference:
As a conclusion
This is of course a small part of those models that are posted on Thingiverse, and new projects appear every day.
If you do not have access to a 3D printer, you can:
do a search on hackspaces in your city, as a rule there are 3d printers, and they are available for small orders
search for fab labs, there 3d printer should also be
