Sorry the photos are not that great. I did not use any support so the loops did not turn out very well. I also used a digital caliper to check the filament, here the results:
Black:
First end: 1.75mm
Middel 1: 1.70mmMiddle 2: 1.74mm
Middle 3: 1.79mm
Other End: 1.77mm
Yellow:
First end: 1.72mm
Middel 1: 1.67mmMiddle 2: 1.67mm
Middle 3: 1.69mm
Other End: 1.68mm
Blue:
First end: 1.71mm
Middel 1: 1.71mmMiddle 2: 1.71mm
Middle 3: 1.70mm
Other End: 1.72mm
These numbers seem pretty consistent with other brands I have purchased. H and H 3D Plastics manufactures its filament in the United States. This along with a great product make it hard to buy elsewhere. I plan to purchase some spools from them and will do some follow up reviews. Till then check them out.
