| ♠Pulling Friction is calculated as the average force required to pull 1.2 meters of 1.75mm PLA filament through 1 meter of tubing at a constant speed, relative to 1 meter of cheap white reference tubing. Note that although we observed the friction of the TL series to be about the same or even slightly lower than our XS series, it also has a larger internal diameter. |
| §Other Bowden tubes may vary significantly in stiffness, depending on the material from which they're made. Our tubing generally tends to be more flexible than most, with the TL being more flexible than XS. |
| ¥Young's Modulus (YM) is the measure of elasticity of the material. Our XS Series additives give the PTFE a slightly greater YM than the TL Series. |
| ♥Temperatures were approximated by heating samples of all tubing simultaneously, observing how quickly each one began to deform. Printer failures may happen at significantly lower temperatures. |
| Printing high temperature materials may create dangerous off-gassing. Please refer to the Safety Page. |

Great Toy
Size: One Size
My three year old loves to play fetch and this dog toy was perfect for him. With the bright, signature orange and blue colors, he can easily spot it when I throw it even in the night. He really loves it when it bounces on the ground as he prefers to jump up and get it. The toy has been through a lot and so far he hasn't chewed through it yet as it is very thick for him to get through.

Lasted whole five minutes!
Size: One Size, Size: One Size
I received this last night and did a cute "unwrapping" this morning for my dog, who was thrilled to get new balls. Unfortunately, the excitement was short-lived. I know the description says this isn't a chew toy or for aggressive chewers, but lasting only five minutes is ridiculous. You can see in my photo that it ripped from a single bite while my pup was just pulling the ball. I thought that was exactly what this toy was designed for!

Super fun!
Size: One Size
Our GSD loves this toy whether playing with it by himself or with us - he grabs the rope and flings it then chases it…it’s become his favorite toy!

Dog loves it, but it comes apart pretty quick.
Size: One Size
The dog loved chasing it and playing tug-of-war, but it lasted less than 30 days. If the outer rubber portion of cover was thicker, or all canvas material, it would probably last for a few months of rough play. May buy again if I can't find something similar to try.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.
