| ♠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. |

Must Read Book To Improve Health and Aging
Format: Hardcover, Format: Hardcover
Jessie Inchauspe is brilliant. This book is full of very useful and effective information building on her 10 Hacks found on her YouTube videos. As a biochemist and medical researcher, she is considerably more knowledgeable than many physicians I've met about nutrition and its impact on health.
I have been struggling with borderline diabetes/pre-diabetes for years. Doctors wanted to put me on Metformin which I refused as I’m improving and reversing this condition through diet, exercise, and natural supplements. This is a very interesting easy to read book that fully explains how important it is to balance and flatten glucose spikes and improve insulin sensitivity.
Many people know ”What” to eat and what foods to avoid, intermittent fasting addresses “When” to eat. This book discusses “How" to eat in a particular order to noticeably benefit health. She explains glucose spikes and insulin resistance and its relationship impacting health, chronic illnesses and aging. She states that chronic diseases including heart, cancer, obesity, diabetes, dementia, PCOS, and others are from inflammation stemming from uncontrolled glucose spikes. Feeding children in this particular order can also improve their health- childhood diabetes is a major concern.
Inchauspe cites a 2015 Cornell Study which found that people who ate food in this order (described below) reduced glucose spikes by 73% and insulin spikes by 48% within 2 hours, along with a significant reduction in their A1C levels. This is huge! My own blood testing and eating a variety of foods in this order, including various desserts, shows an impressive further reduction in my 2 hour postprandial blood glucose readings which are typically in the 90's or very low hundreds.
The 10 Hacks found in her YouTube videos are greatly expanded upon in this book to make these hacks even more effective in normalizing glucose and improving blood testing and A1C scores, while helping to lose weight by eating foods in a certain order: First- salads and/or veggies. Second- protein and good fats. Third and last- carbohydrates & starches. Yes, you can eat whatever you want, and however much you want (no counting calories) and even have dessert as part of the meal while minimizing glucose spikes and fat storage, improving insulin sensitivity and overall health. If you need to lose weight or have blood glucose challenges, skip dessert and reduce or eliminate bad carbs and limit good carbs. Eating in this order becomes a lifestyle and easy to implement daily. I find eating this way that I’m already pretty full by the time I get to the carb and dessert stage which helps maintain my weight. Other hacks include drinking a tablespoon of apple cider vinegar in water or in a dressing, not eating naked carbs (take carbs with a good fat or protein), and walking after a meal or doing slow calf raising exercises while seated at the table.
I have been doing intermittent fasting for over 6 years and it has been a major driver in my own improvement in reducing A1C scores. I get my blood tested every 4 months. I vary fasting between OMAD ( 1 meal a day), 20:4, 22:2, 19:5, 18:6, and 16:8 depending on schedule eating no more than 2 meals a day and no snacking. Fasting reduces inflammation which is a main driver of diabetes. I’m doing a modified keto diet mainly with healthy whole food items. Combining fasting wth eating food in the proper order is effective in reducing glucose and easy to implement.
Doing calf raises while seated which target the Soleus muscle in the calves is very powerful. The Soleus muscle is the only muscle in the body which absorbs glucose from the bloodstream. I try to do calf raises while sitting at the dining table at the end of a meal for at least 10 minutes. This can reduce glucose spikes by 52 percent and insulin by 60 percent. Google the ‘Soleus muscle glucose metabolism’ for more info. I also do a few simple Tai Chi exercises I found on YouTube.
I have also been taking Dihydro Berberine which is more effective than regular Berberine. I use Heal Meal brand. My functional health MD upped dosage to 5 a day- 3 at first meal, 2 at my second and last meal- which has reduced my glucose spikes in a major way versus 4 daily. Take 20 minutes before eating.
Highly recommended!
Update September 2024- I recently got a Dexcom G7 continuous glucose monitor (CGM) which has been very educational in seeing how good quality sleep and walking after meals helps to further lower glucose levels, versus poor sleep and no walking after eating. Drinking a 1-2 tablespoons of apple cider vinegar in a glass of water before a meal, especially a high carb meal, is very powerful in reducing glucose spikes.
I used to get up at 3am to go on the computer every morning. Forcing myself to break this habit and stay in bed has seen a further lowering of blood glucose after several days. A good night’s sleep and exercise after eating are as essential as diet.
This is clearly shown on the CGM which reports glucose changes every 5 minutes. Seeing how various foods impact glucose is a valuable learning tool. I had to pay for this out of pocket and it has been a worthwhile investment.
When installing a new monitor every 10 days I find it necessary to recalibrate the Dexcom readings with a fingertip blood test, as the initial readings were too high, typically anywhere from 10-35 points higher than the blood test. Simply click on the plus sign and follow directions to recalibrate.

Revolutionary Health Guide That Actually Transforms Daily Wellness Through Practical Science!
Format: Hardcover
Glucose Revolution has been absolutely transformative for my health understanding and provides exactly the actionable, science-based approach needed to optimize energy, weight, and overall wellness through blood sugar management that actually works in real life! As someone who struggled with energy crashes, weight fluctuations, and general wellness concerns while wanting evidence-based solutions rather than fad diet approaches, this book delivers the comprehensive education and practical strategies that make sustainable health improvement achievable through understanding glucose impact on daily functioning.
The scientific foundation is outstanding with clear explanations of how blood sugar affects energy, mood, weight, and long-term health while making complex metabolic concepts accessible to readers without medical backgrounds. The research-based approach provides confidence that recommendations are grounded in genuine science rather than marketing trends or unsubstantiated claims.
What impressed me most is the practical application focus that translates scientific knowledge into daily habits and food choices that actually work within busy lifestyles and real-world eating situations. The actionable strategies eliminate the gap between health knowledge and implementation that makes many health books intellectually interesting but practically useless.
The meal timing and food combination guidance provides specific, implementable advice about optimizing glucose response through strategic eating patterns that don't require extreme dietary restrictions or complicated meal planning. The flexible approach accommodates various dietary preferences while delivering consistent metabolic benefits.
The energy stabilization benefits have been genuinely life-changing with elimination of afternoon crashes and dramatic improvement in sustained energy throughout the day that supports productivity and overall quality of life. The consistent energy demonstrates real metabolic improvement rather than temporary dietary effects.
The weight management insights explain the connection between glucose spikes and weight gain while providing sustainable approaches to weight control that don't rely on calorie restriction or unsustainable eating patterns. The metabolic approach to weight management proves more effective than traditional dieting methods.
The food selection strategies help identify which foods support stable blood sugar while showing how to modify meals and snacks to minimize glucose spikes without eliminating entire food groups or following restrictive eating plans that become impractical for long-term adherence.
The lifestyle integration makes glucose optimization practical within normal social eating, dining out, and family meal situations where extreme dietary approaches become socially isolating or practically impossible to maintain consistently over time.
The educational value extends beyond glucose management to comprehensive understanding of nutrition science and metabolic health that supports informed food choices and health decisions across various wellness goals and life circumstances that require adaptable health knowledge.
The motivation enhancement comes from visible, measurable results that demonstrate the effectiveness of glucose management approaches while providing sustainable motivation for continued healthy choices that don't rely on willpower or temporary enthusiasm that fades over time.
The long-term health impact addresses chronic disease prevention through metabolic optimization while providing proactive health strategies that support aging well and maintaining vitality throughout life rather than reactive approaches that address problems after they develop.
The accessibility makes advanced nutritional science understandable and applicable for readers regardless of previous health education while providing depth sufficient for those wanting comprehensive understanding of glucose metabolism and its health implications.
The value for transformative health improvement is exceptional for a book that provides education and strategies equivalent to expensive nutritional counseling while delivering lasting knowledge that supports lifelong wellness enhancement through practical, sustainable approaches.
For individuals seeking evidence-based health improvement that addresses energy, weight, and overall wellness through practical strategies that work within real-life circumstances while providing genuine understanding of metabolic health, this book delivers exactly the scientific foundation and actionable guidance needed for sustainable health transformation without extreme measures or temporary solutions.
