Print In Place Platform Jack

I found this awesome print in place platform jack from Thingiverse user Intentional3D http://www.thingiverse.com/thing:925556/#files.

Unfortunately, my printer wasn't happy with the way the screw mechanism was designed, so I made really simple modification that allowed me to print it successfully.

It's a really impressive model by Intentional3D and it makes a great demonstration about how complex 3D printed parts can get, even when they are print in place designs.
