Print3r: Cookbook

A few useful recipes for using print3r:

Just A Quick 20mm Cube

print3r --scad print 'cube(20)'

and to save filament, print it with --fill-density=0 or use @hollow:

print3r --scad @hollow print 'cube(20)'

optionally use --random-placement to place it randomly on the build plate.

Simple Rectraction Length Calibration

This way you easily and fast find your retraction length, change the value from 4 to something else:

print3r --random-placement --scad --multiply-part=2 --retraction-length=4 \
   print "cylinder(d1=3,d2=0,h=10)"

which prints two cones, easiest and least material usage retraction calibration.

Scale Part to 30mm Height

print3r --scale=0,0,30mm 3DBenchy.stl

X and Y are scaled proportionally so 30mm Height (Z) is reached.
