This was done for my 3d modeling class (4170) using AutoDesk Inventor 2009. It was done to show how a basic combination lock works than to actually lock anything. It is made of 10 parts and fully works. Cost to make was around $28 to have it printed on a Dimension 3D printer.Total size is 4 inches wide. 3.5 front to back and 2.5 tall and very lightweight 2-4 ounces. (correction1.5 Ounces)

I got the idea from this website Woodgears.ca This is my version.

This was added to the Makezine site and I figured I would add it here also and throw in a few renders.

That's awesome! You should put up a file so other people can make them. That's really cool
<p>He did, look on thinyverse</p><p><a href="http://www.thingiverse.com/thing:2047/#files" rel="nofollow">http://www.thingiverse.com/thing:2047/#files</a></p><p>Great project!</p>
Interesting project<br><br>I would love to see it added to the 3D print group I have just started<br><br>http://www.instructables.com/group/3Dprint/<br><br>Thanks
it looks like styrofome
&nbsp;i have a plotter and A educational place here in Nj sells the program and the paper to peel and stick your way to a prototype THAT IS JUST fine for me,as I build everything I can and if I CANT GOD GAVE ME MIKE!
Cool. I made a toy train in cad and a wooden air powered car toy and a few other things but this is beast.
Wow, sounds cool, you should do a slide show or video about what you've made. Just a suggestion. : )

I cant get to it. Its at school. Anyways I havent made a prototype thing. I dont even know how to make screen shots.
Aww that's a shame, but just a tip, for screen shots, hit Alt + Print Scrn, the key to the left of f12.
Also,Alt can be removed but then it takes all your programs in the shot.Alt makes it capture the active.
were can i buy or use a 3d printer?
Wait a year and someone here will post a diy version
Wait 50 Years and people will be throwing them out :P
hihi 3D for free.
you said people will be trowing them out. so i said free 3D i wanna have free 3D

no morle like in nitromethanol (glow fuel)
My profile contradicts my statement.

i know i'm right...
Whatever :P
blah *BANG* lost my head<br/>
LOL I don't think that would work well. If it did work it might melt or run bad.
