I "enjoyed" this last week when I tried to design threads compatible with European milk bottle. Important dimension is thread outer diameter 38mm, there are 3 threads with 3mm spacing, so spiral is 9mm per turn. But fun starts with tolerances and material. Printed cap works with original battle, printed bottle neck works with original cap, but both printed parts do not work together, cause PLA is too tough, has sharp edges and there are 0.12mm steps from layers. I used telephotos at minimal focus distance to get the profile without much distortion and calibrated it from known dimensions and used it for measuring profiles. Cap is much more complicated design than it seems and cap has three points of contact - there's like 3mm long (i don't remember) pipe which extends outwards a bit and this goes inside the bottle, makes contact with inner wall and bends inwards. Then there is other tiny ring that pushes agaist outer chamfer/wall on the very top of bottle and bends outwards. Then finally bottle pushes against the lid. But lid is made from soft polyethelyne and for 3d printing I'm not aware that other soft materials than TPU/TPE exist and these are not convenient to print/dry.
Been wanting to do this for ages, have these glass bottles with no lids that I need, followed your guide and the first print worked! Need to tidy up a few little things but all good. Now to learn how to put a texture on the outside of the lid. One stupid question, I can't figure out how to change the view of the object apart from clicking top, left etc up in the right hand corner, how do you simply click the mouse and drag the object around?
You click with the wheel on your mouse and then move around. If using a laptop, I believe you hold down shift and click and move (I may be wrong about the laptop). I have a video on my channel about it!
Rotating the object view (orbiting?) is done with the middle mouse button. Panning (ie dragging up/down/left/right) is SHIFT + middle mouse button. The above assumes that the "Pan, Zoom, Orbit shorcuts" setting in Preferences is set to PowerMill.
@@ShopTherapy623 lol, simple, thanks for that, brain was half asleep, you wouldn't also believe I just re-started 360 after an update and the very first tool tip that came up was the exact thing, how to move the model around. Thanks, brilliant simple video too that explains it very well.
@@ShopTherapy623 I have to admit though. I made several before it would work :) And it's even more aggravating with resin prints instead of filament because the coefficient of friction doesn't want to cooperate - resin binds depending... Thanks for commenting.
That was cool to watch. Thanks for explaining things so well.

very helpful video, thank you ❤
I did this with a soda bottle to make a aquirting nozzle. Except I made the model in MoI 3D.
Great tutorial and explanation
Super helpful. Thanks
Thanks, just starting out in fusion , but i was very clear and usefull . Picked up many tips !
4 years of industrial design college and they didn't teach us any of what you just taught me in 30 minutes!
Well explained!! ;)
Thanks for watching!
I like it, nice and simple! What version of Fusion 360 are you running?
I have an educational license!

I create the thread by itself, then I boolean out it's mated part from that as well and scale it for gap.
Having a male and female threads is totally fine. I prefer having two male threads. They seem to work better.

Why not just use the thread maker tool?
If it’s a standard thread size, you definitely can.
