Toothpaste Squisher

I designed this in millimeters, but Cura 15.04 seems to read it as nanometers. I had to set the scale in Cura to 64.7 mm Y (lock the dimension scales (uniform scale) together to get it to the right size.

I took PrintTo3D's "extruder", and had some trouble getting the scaling right. Plus I didn't like some of the proportions, and sizings, they didn't fit well on the Crest (c) tubes I use. This is the Gen 2 of my design, as I originally made the walls much thicker then required, and the gap was a bit larger than I anticipated. This one is currently on my printer, using much less filament, and time.

I also dislike how infrequently makers upload the original file. I create in Autodesk Inventor 2016 (currently) student edition, and will try to always upload the original .ipt when I upload a .stl, so others can work on the original file, and make/adjust/improve.

Update: 20180923- Updated the files (I hope) to actually print correctly at 100% scale. Inventor natively outputs so
