this single print paid for my 3d printer

Custom threads in f360? That's the real winner of the video

For your first design, try chamfering the end of the dowel before trying to jam it into the newly formed threads. This should provide a ramping start-of-cut and may help with the self-alignment

They didn't have special machines or tools when they made those old woodworking benches. They drew on a spiral on the dowel, sawed a kerf along that line and then used rasps and files to form the threads.

"I bet Jesus could do this with hand tools..." What a great line! 😂

I'm a simple man. I see a Swedish Maker video, I watch and like. Edit: MORE COW CAMEOS! I'm so jealous you have cows. I love cows.

Don't sweat the cows. They sound much better in the background than sirens and g_nfire. I love your life, too!

I'm sorry, but can't you print the thing like in the first iteration of this project but based on the last iteration of internal threads? Just take this box with internal threads, remove half of it and add a hole for the blade? Wouldn't it let you to not print this long external threads thing but just use one little box for the entire length? Maybe even combine both ideas and use this new internal thread support in the front and the currently working external thread thing in the back. So that you get your wooden thread to begin with your solution and then continue by just pushing it like the previous guy did. I don't know if it'll work, but I guess that you might save some printing material without printing this long external thread thing

I would say to 3d print a section of the final threaded dowel that you can mount on the front end of the dowel. Then you could use that to get it started through your original jig and then once the bit starts cutting the threads, that's what will pull the dowel along as you twist it. Not all that different from your idea just with the advantage of having to print a shorter section and not needing to reposition the or print a really long thread like you did. But goo perserverance in hammering out the problem.

Perseverance is the final take of this video, and this is what you have with every video you do. You do not give up and neither should we.

2:28 There's a saying in Dutch: "people only close the well after a calf has drowned". This on is putting it to the test.

I think the cows were looking blank because you were speaking to them in English 😂 great video.

My favourite part was calling all the female cows with udders him. The thread prototyping came in a close second, great video

Congratulations on passing the Engineering 101! The thread experiment oughta have given you a solid feel for tolerances, and when it comes to mechanical engineering, that's seriously half the battle. Amazingly done! I look forward to seeing what this actually will come out as.

That was very enjoyable for many many reasons

Push all thread faces/planes 0.2mm inward. Don't just "scale" the entire thing.

That's genius! My first conclusion to modifying custom threads was to model and spiralize them. But you found a more elegant solution. Also I really like that you haven't given up and found an ingenious way to solve the problem.

Now thats really nice to know! I wasnt aware that you can make your own thread definitions like that. In the past I've made custom threads by guiding a profile along the path of a coil. Create a body (with a triangular section), create a sketch with the custom thread profile you want. Then sweep that profile along one of the triangle edge of the coil.

I love this video. If engineering is the art of solving problems, that's exactly what you did. Prototype, get feedback, iterate, and just kept going until you got your result. Thank you for sharing

Great to see your rethinking the problem and coming with a different solution. This is literally thinking from the inside to outside the box (threadwise)

As someone playing a bit with wood and 3D printing and trying to get back to 3D moddeling, I can tell you that you perseverance is worthy of respect. I totally understand the frustration of going back and work on new iterations but I'm certainly not as good as you haha, well done!
