| ♠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. |

Strong Suction Cups
Color: Silver
I didn't realize that this caddy came with the option to use suction cups or adhesive hooks. I opted for the suction cups and was pleasantly surprised at their strength. I loaded the caddy up with a couple of sponges, fingernail brush, and a dishwashing brush (filled with liquid soap) and have had no problems with the caddy remaining strongly secured. It's a great little organizer and looks really nice.

GREAT Suction!! Looks fantastic!
Color: Silver, Color: Silver
I wanted to find a sponge holder with great suction for our ceramic sink. This is the REAL DEAL! I saw one or two complaints on the reviews below but obviously they are doing something wrong, because if you just follow the instructions (make sure the sink is clean and dry where you stick it), it works perfectly. I've had it for about 3 weeks now and we use it every single day and it has never slipped even once. The suction cups are big and made of good plastic so they really do the job. It hasn't budged from the spot where I placed it. It's also easy to take the caddy off of the suction cups when you want to clean the sink without moving the suction cups. You can peel them off easily and reposition them but they will not move unless you want them too. It's also the perfect size and looks great. Perfect for holding a stick sponge upright so that the soap doesn't leak out of it.

Great product. Suction can be improved though.
Color: Silver
I'm satisfied with my purchase. It gets the job done. The suction pads can definitely be improved though, I found that pads couldn't keep the holder in place for more than an hour so I just removed the suction pads and kept it beside my sink. Overall, great product. Would definitely recommend.

It actually sticks to the sink and stays where it is supposed to. Well made. We love it!
Color: Silver
Finely, a sink caddy that actually sticks to the sink! We have been so frustrated trying to find one that does. This one is great. We just used the suction cups, which are large and there are 3 of them. If finely actually stays there!

Works & Looks Great!
This item comes with two options for sticking to the sink, suction cups & an adhesive thing. I decided to try the suction cups first, that way I can remove them to clean, plus I wanted to test out the position of where I put it on the sink. They work great! I haven’t had to re-stick not once. Great staying power! And it looks really good! Also, the seller sent a follow-up message just to check in & offer answers if any questions arose. That meant the world to me, like it’s not every day a seller cares what you think once money changes hands. 10/10 would recommend!
