Holy moly Rocky.

I have found them on digikey before.

Try changing retraction amount from 2.5 to 1.00

Alright I tried printing a single walled thing again first with an extrusion multiplier of 1 and retraction set at 1.00mm that ended with a print without a single hole, but a thickness of .69mm (left) and again with extrusion multiple of .61 that ended with giant holes and a wall thickness of .60 in the areas with only small holes. (right)

Here's a bit better picture of the two prints.

My retraction acceleration is currently set at 3000.00, that's the only thing I could find in repetier that was obviously a retraction setting.  This is my first experience with a 3d printer, sorry for being such a complete noob.

One thing that might make holes is too much retraction.  Do they always happen at corners or layer changes?

I saw an example of printing with PLA with the same result and the same item without any strings...

The difference was a fan.

According to the write-up, PLA takes longer to cool so you get less adhesion between layers, printing slower will help, or make sure you have a fan on the plastic. Some have just used a house fan to blow on the print, but that may also cool your extruder.

But, I forgot to ask if you have a fan mounted to the extruder blowing on the print itself? -- ggunners

how small of a desk fan are we talking about?

I do not currently but I have read that a fan helps out alot also

1) download this http://www.thingiverse.com/thing:38129  it is quick and easy to make. I printed several just to have on the side.
2) Print. I prefer 60% infill to help prevent any wobble
3) Mount to the wooden block and screw fan to print with
4) Toss on the 40mm fan and tighten to prevent wobble (too tight and the print will crack)
5) Wire up the 40mm fan
6) Repeat all steps excluding 1

Of course...if you have a case, it is recommended you remove it. You dont want too little or too much air hitting the filament as it is extruding. But...BUT! you could eternally having the desk fan on when printing PLA. It would take up space and be and eyesore, but would bypass the given steps I took.
