Implant .STL Won't Convert to GCode

[Roxy]

Here it is, wont convert to GCode.

Is it really going to take up so much filament??

Any way to reduce amount of filament, make it hollow or out of hexagons or something?

First, a 3mm wall dividing the boxes is probably excessive. That can be cut down to 1.5mm. But maybe it makes sense to not make the wall solid. It can have all kinds of different infill at different fill levels. We can chop that 40m of filament down to 10m I bet.

But anyway... It sliced just fine with Slic3r 1.1.7 I have a really fast machine, but I did notice a 20 second pause when it was generating the perimeters. I think you just need to let it sit and chew on it for a few minutes. (I have lots of memory too... That really helps when you are slicing.). Give it 10 minutes before you kill it.

At the end of the attached GCode file, it says all the settings that were used to slice it. At worst case, you can just duplicate those settings and it should slice on your machine.
