Just a clarification – when I said our 3.00 mm = hollow, I meant that the type identifier icon is hollow. Not the filament! BTW, our curent promo at Amazon (up to 20% off, free shipping) ends this weekend.

For those of you that love our ABS and PLA filament, we just recently restocked our inventory at Amazon so that you can get it with free shipping. (2 days with Prime.) There’s plenty of colors of ABS and PLA, in 1.75 and 3.00 mm.
For quicker browsing, look for the filament type identifier icon on the label:
PLA = circle
ABS = triangle
HIPS = square
1.75mm = Solid
3.0mm = Hollow
