This was for a final project for my 3D modeling class. I went with a Combo lock. It was done to show how a basic combo lock works. Total size is 4 inches wide. 3.5 front to back and 2.5 tall and is made of 10 parts.

I was going to do a Anniversary release of the files, but I am releasing it sooner because I get asked every once in a while about the .STL files or the Inventor.IPT files so here you go. Enjoy.

Inventor IPT files are for Inventor 2009

Just built this one following soapy's advice, and it worked out perfect!

This model doesn't actually work as uploaded.

Either you can spend ages messing around trying to modify the parts once printed, or, you can simply stretch the spindle
&
amp; rear disc part by ~25% in the Z axis (to lengthen the spindle) and it should go together far more easily.

awesome model, can't wait to print this. quick question, are the stl files orientated in the correct direction for printing? the base looks like it will need a lot of support

This is just downright awesome..! great model. Now Im really wanting support material for my MakerBot.!

I'm not 100% sure because I'm still waiting for my makerbot to get shipped, but looking at the individual components, it looks like this can be printed without support material. You might have to slightly modify the model so the base component can be printed in two parts so they can both be printed flat.
