Good on you for doing a fix and eventually a recall. It's such a pain when the best orientation for supports is the worst orientation for strength and that pretty much is always true for printing threads.

Cool that you let us know even about the mistakes included in your designs. I have been there myself and it is really appreciated! Thank you and keep on the awesome models. I will reprint my part just to be safe, although it worked perfectly for me so far.

One of the top channels about 3d printing ! You are a true engineer !

Thinking of 3d prints in a similar way to how wood grain affects strength is useful. Also like concrete they have loads of strength in compression and very little in tension. The prints have minimum strength between layers and maximum along the layer. CNC Kitchen is a good resource.

Thanks for the dedication to your craft, very impressive work.

You can tilt the part slightly by 5-10°. This way the layer bonding gets stronger in vertical direction. Also 0.1 to 0.15 layer heights and less cooling helps as well.

i've noticed my slicer do things like this once or twice before where it will do weird things with partial layers under certain sections, but sometimes it will do solid layers... Either way. i think if i needed a part like this to be super strong i'd design it to have screws go in past the potential break point so they will hold both sections together.

Am in being stupid or am I missing some information about the print settings. I'd love to know the recommended infills for the different parts. It's my first time printing TPU and not sure what infill to do the gears

I have been using the router 2.0 for about 6 months now and have not had an issue. I appreciate you finding and fixing it. I must admit however I am fascinated by the “new” tool your testing. It’s a rotary is it not? Can’t wait to see it in action

Thank you, not sure what its actually called. here is a link to it:kzread.info/dash/bejne/nK2busmtY5bKcdY.html

Respect!!

I think this can be avoided anyways with proper slicer settings for the affected layers.

what do you print in? PETG?

some slicers will let you set per-layer instructions and settings, e.g.: tell it to print 100 percent infill for 20 layers through that area and then return to whatever settings the rest of your part uses

I believe Simplify3D does this, as well ideamaker. you could also slice the model as 100 percent once, the lower infill once, and copy the gcode from the 100 percent infill model for the layers you need and replace it.

So if we purchase the STLs and you come up with a fix, advancement or a upgraded version, do we have to purchase those STLs too?

As long as its an improvement or fix of the mistake it is for free. So far all new versions have been for free. But if its a new model with big changes and new mechanisms then it will not be

Putting 4 or 6 small screws wont fix the problem? I know may sound stupid but instead of pure infill additional hole with screw might help a bit (also gyroid infill might be better). or better yet holes through whole model, on one side brass insert on the other flat head screw.

yeah i was thinking the same. would make it a lot stronger for the price of a few little screws, even with the improved/proper slicing.

@@ge2719 I did something like this in my car for broken sunvisor holder. Original made from ZnAl is available but costs something like 80USD plus shipping, so I did the thing with ASA and M3 brass insert. It works very good so far, after half a year sunvisor still didn't sag at all and can be put in whatever position you want them to be (just clamping force of a plastic).

@@BOTmaster15 nice. I broke my rearview mirror in mine, the part that slides over the metal bracket on the window cracked off at the side. Was too thin to put screws through it but could seek through anduse some copper wire with epoxy....wasn't a perfect fix though, it's gradually becoming loose. Hopefully when I get the hotend upgrade for my ender 3 i can print a heat resistant plastic replacement. I imagine pla will just melt off in the one day of summer we get in the uk :p

Anything Can be 3D printed. But this does mean that everything should be 3D printed. Each thermoplastic have its own range of use, which does not cross every application, especially when the part is 3D printed, because a 3D printed part is not isotropic, so it brings strength issues compared to the same material injection molded. Last but not least, other materials will be much better for this application while decreasing the cost. On the other hand different manufacturing process will be much faster with simple tools. It could be seconds versus hours. Last, don't underestimate standard parts, which are ready made perfect with an unbeatable price tag. I appreciate this can be so entertaining to design and produce a whole product by yourself from scratch and out of your 3D printer. It can works fine, sometimes, but it is maybe still not a good idea.

Hej Alex, I agree on the standard part argument (the price tag is mainly unbeatable for the industry…). The advantage of 3D printing is for sure not time and cost. It is local production on demand and replacement parts are unlimited (no tools, no company, no minimum quantity). It is interesting how we can cover the downsides of 3D printing and standard parts is a good approach✌️!

@@efficincy the point was: everything does not deserve to be 3D printed. Another approach is "the 3D printing paradox" which is an early 70s study which explains additive manufacturing is only good at what is long and complex to be made by substractive manufacturing (A.K.A. traditional manufacturing). For example, it is stupid to print a front panel, because you make a nice and strong front panel in no time just by drilling holes into it. What we see currently, and what is IMHO the worst downside of 3D printing, are people designing complex parts or systems for the only reason it's yet printable. The job of the engineer ( pro or not) is to optimize the right part at the right place, considering all the possible manufacturing or providing ways. About the local manufacturing, 3D printing is not the only way, it is not really sustainable by the way as you need filament. Local manufacturing is a whole world involving all the manufacturing methods, from hand made to traditional to any digital manufacturing. 3D printing covers only a small field in this topic.

You hit the nail on the head with one line though. An unbeatable price tag. If you already have a 3d printer at your disposal, a person could print 50 replacement parts for the one that he found to fail, and still not reach the price point of a kreg router lift. For a hobby woodworker the price point is not unbeatable. For a professional, it's a cost of doing business. This puts a luxury item in the arsenal of people who otherwise wouldn't be able to justify it.

Я снимал видео для нового инструмента, когда это произошло. Это произошло из-за того, что я несколько раз поднимал маршрутизатор слишком высоко. Поэтому я решил пройти этот тест еще раз, чтобы подтвердить проблему. Я взял почти ту же модель, напечатанную в марте 2022 года, чтобы протестировать это. Эта проблема могла быть вызвана не только прямым воздействием , но и проблемами с геометрией. Несмотря на то, что изделие N: 17 было спроектировано как цельная модель, слайсеры все равно разделили бы его на две части в нижней соединительной части. и распечатайте его с нижним и верхним слоями вместо стенок и заполнения. Я не замечал этой проблемы, пока не получил электронное письмо с решением этой проблемы две недели назад. Я исправил геометрию и обновил файлы 22.11.10, но я никого не уведомлял, потому что думал, что это все еще достаточно сильное соединение. Я протестировал его вручную и не увидел никаких проблем с подключением. Пока это не произошло 11 ноября 2022 года, во время съемок нового видео Но, как вы можете видеть, я действительно сломал другие части маршрутизатора, но все равно не смог сломать то же самое место. Не уверен почему; может быть, это потому, что я напечатал его с большей скоростью, чем требовалось, потому что я устранял проблему во время съемки видео и спешил. Пожалуйста, перепечатайте пункт № 17 еще раз из обновленных файлов для более надежного соединения. Но я все еще думаю, что главная проблема не в принте, а в самом дизайне. Я разработаю новую версию в ближайшие 3 недели, чтобы устранить эту проблему. Я очень сожалею о своей некомпетентности.
