Yes but I'm not sure you'd get the accuracy you're after. Have a look on
Thingiverse, there's heaps of gears and worms etc.
I test printed a couple of gears from Thingiverse and a couple I generated myself using
geargenerator.com - they seemed to be good enough to make a barndoor tracker, which is what I was planning but never got any further than testing.
Also, I'm not sure why a PLA printer needs a heated floor? I thought that was just for ABS?
