That was for .3mm layers
.1mm layer should take 3 times longer I assume

I don't think it is exactly 3 times longer, or at least does not appear to be from what I've experienced myself.

ABS has
a density of 1.04 grams per cubic centimeter, so a 1kg spool should be
about 962cc. The nominal cross-sectional areas of 1.75mm and 3mm round
filaments are .02405 and .07069 square centimeters, respectively.
Divide the volume by those areas and you get a length of 39976
centimeters / 1311 feet for 1.75mm and 13603 centimeters for 3mm.

115.6 cc =  95 grams  1cc = .82 grams Finished
density of 1.04 grams per cubic centimeter

I figure 4 cents a cc which weighs 1.04 grams.
My sd2 uses about 12 cc an hour so 1k should last about 80hours

Can we use those calculations?

115.6 cc =  95 grams  1cc = .82 grams Finished
density of 1.04 grams per cubic centimeter

I figure 4 cents a cc which weighs 1.04 grams.
My sd2 uses about 12 cc an hour so 1k should last about 80hours

so 413M maybe 400m then so

so 0.11/cents per meter still great value

using the slicer estimate of mm used and the fact that I estimate a 2lb reel of my SD white ABS is about 500 meters

$43/500m = 0.089 cents per meter. My v8 bloc which is pretty detailed. was about 12 meters $1 and the iphone case was 3meters = 0.27cents

pretty good deal.
And after a week of printing about 1x thing a day I probably only used 20meters or less At that rate I can probably run for 4 months or more!

I'm seeing the average cost of each print to be somewhere between $0.50 and $1.00 in raw material costs.  Larger prints are a bit more but not much.

Here is a list of everything I've printed on my first spool:

(all prints at 0.3mm unless otherwise noted)
Portal Companion Cube x 3 (dime sized 0.3mm)
Portal Companion Cube x 1 (dime sized 0.1mm)
Godzilla mini-diorama
B-2 Stealth Bomber (0.1mm)
Minecraft Chicken
Command and Conquer Tank
Minecraft Creeper
Minecraft “Steve” action figure
Minecraft “Skull Island” map section (+1 partial failed print) (large)
Starcraft Protoss Nexus
Snowman x 2
Failed Dial indicator holder print
Failed Blockbot plate 1
Pin Test (to see how big holes need to be for pins to go in)
Sunshine Egg Mold (custom design)
Blockbot Transformer (large)
Winterfell (0.1mm && 0.3mm)
Cinderella’s Castle
72 Tiles of Carcassonne (this was about 21 separate prints of 1-2 hours each)
Levelling thumb screw handles for Printer
Clamps for printing on glass

There might be a few one off prints that I've forgotten, but that is pretty much all of it.

Most of this stuff you can look up on Thingiverse to find them.  A large portion of the end of the spool was used for the 72 tiles to make a 3D Carcassonne tile set for the board game.  I'm going to do Catan next.

Overall I'm happy with how far a spool of plastic goes.  I never feel like I need to ration myself or think about how much something is going to cost.  I got my Solidoodle at the end of November and am just running out of my first spool (end of February)

Anyways, hopefully this will help someone looking into buying a solidoodle.  Very happy with my purchase so far.
