I'll admit that I'm very new to all this (ten days) but I just downloaded a 'Nautilus Gears' file from Thingiverseand I'm getting a print time of 25 Days 11 Hours 58 minutes, with 1721.85m and 5136g... It comes in as two separate files, gear and support bar, and I multiplied by 1 copy to get the two of each required. I did try printing it but it started putting weird 'connecting lines' (to features that don't apparently exist) over the first layers. What am I doing wrong???
