Fusion 360 for 3D Printing LESSON 13: Designing 3D Printable Involute Spur Gears in Fusion 360

Guys I will be teaching how to use Engineering Calipers, and they will be an important part of most future lessons. You can get the calipers I am using at the following link:
amzn.to/3mPymGM
You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this class we will be using the Creality Ender 3 V2 Printer. Your life and my life will be easier if we are working on the same hardware. You can pick up your printer on amazon at the following link: [affiliate link]
amzn.to/3GaGn25
You will also want to stock up on some filament for your printer. I like the eSun PLA. Here is a link to what I am using:
amzn.to/3yXhYLz
The link shows you can get different colors. I like the orange.
In this lesson we will describe the fundamentals of Involute Spur Gears. I will show how to design Involute Spur Gears in Fusion 360. I will design and print an example of a simple gear box with two gears, and then print on the Creality Ender 3D printer.

Amazing lesson!! I've always was fascinated by gears, when I used LEGO. Like how when one gear moved clockwise the other one moves counterclockwise, and speed and torque being inversely proportional. Never knew so much math went into gears!!! That is SO cool! By the way, at the end of the video you were talking about tolerances, but the reason yours was hardly working is at 29:53 you made it 15.8 instead of 14.8! No wonder it was so tight!! Thanks so much Paul for all you do! Rather than I am legend, YOU are legend, Paul!!

[@gimmeaford9454]

good catch

[@dadberndi]

great lesson and wonderfull plugin! From experience I made chamfers on both the gearholes and the posts to simplify sliding these on!

[@MarshallCrumiller]

Minor nit: when you measure the diameter of the gear, you measure from the top left of the left spoke to the top right of the right spoke. This doesn't quite measure the diameter, as your line doesn't go through the center. If you had measured from the top-left of the left spoke to the bottom-right of the right spoke you would have measured symmetric points and found a diameter not of 77.947 but exactly 78.0.

[@warrenscorner]

Great lesson Paul! I fell behind watching all of the videos. I went back to work after being retired for 5 years. My old boss called me and made an offer I couldn’t refuse. It feels good to be back in the mix. I’m a little rusty with my PLC programming but I’m sure it will come back to me.

[@andyprest]

Brilliant lessons Paul 👍 getting more difficult but I'm sticking with it! Thanks again for all the information you're sharing it's so helpful 👍

[@rickbonari4493]

Great lesson !!!! Thanks to you Paul I am starting to feel pretty comfortable with fusion 360 and cura. I have been able to successfully print out all lesson files and they turned out great !!!!! When printing the nuts and bolts I had to tweak about four settings in cura and the nuts and bolts fit together very well. You are the best teacher on youtube and you and yours take care and GOD bless and be very safe and well !!!!!!

[@leonardbennett7814]

Thanks Paul, I have been using Fusion 360 for a few years but this is a game changer.

[@edSabio572]

Thanks Paul! Coming from a strictly software background, I am very happy to be still standing. Took awhile to finish this lesson. Yet, I am grateful for the material presented in a way that concepts are understood and emphasized. Cura SW gave me an error during slice. I hope someone who had this problem could shed some light on this issue.... Thanks again!

[@scottwait3585]

Thanks for another lesson Paul!

[@cbrombaugh]

Thanks for another most-excellent lesson Paul. I will print your version while I try to design it again by myself.

[@paulmcwhorter]

Fantastic!

[@rlgmedia5364]

Great lesson. I have a use for small 3d printed gears.

[@joshalonzo8488]

needle files are becoming my best friend

[@daviebutao6306]

as always very informative! and each and every day am watching,I learn something brand-new,Thank you so much sir

[@paulmcwhorter]

Glad to hear that

[@mezodgaming5637]

I love your teaching sir

[@9H1RA]

Wow very interesting lesson.

[@asus3365]

Lets go Paul!

[@loptica62]

Again, another great lesson! I love gears... ever since college... btw any chance we'll be seeing bevel gears (or worm gears) in the coming lessons... (only one thumbs up although you deserve at least 10x...) Keep up the great work.

[@jasonrhoades4122]

Yep, I'm havin fun takin these lessons. I just hope I get my printer before the lessons are all done, lol. I've never made a youtube video and I'm lookin forward to showin my prints from these lessons.

[@sehtzek]

Fun project thanks. I need to try again with some more tolerance. The large gear was a little tight. Just a little sanding and it was great. The small gear was much tighter and actually took a bit more sanding. I tried flipping them over and it didn't seem to matter. Doing good and meshes nice with just that little bit of sanding.

[@paulmcwhorter]

Yes, tolerance can vary with your specific printer, and print settings.

[@mikevdwerf]

you have by far one of the best channels on YT ! i learned so much but more so get motivated to go to take the next step! The only think i disagree is that I think tea is the better choice 😉

[@paulmcwhorter]

Mike, Tea is on my approved beverage list. Please tell me you do not put sugar in it though. I very much enjoy unsweetened tea. I have a variety of teas I enjoy, just for me tend to drink more coffee. Hey, thanks for the Patreon, really appreciate that!

[@philluvschips3787]

That's great. Many thanks. Next challenge, can we create a worm gear?

[@snowman58able]

kzbin.info/www/bejne/e3rOlXaKaKt-jLM Above is the link to my spur gear video. Advise: If you have trouble getting your part off the bed,make the bed temperature 90 degrees. Be careful handling the bed it’s hot

[@danny12345]

Thanks for a great lesson can you do a lesson on the math of gears

[@TinFoot]

When Paul instantioned the SpurGear his default Root Fillet Radius is 1.588. Mine is 2.000. When I make all his recommended changes I get a warning that the max Root Fillet Radius is too large. It must be less than 1.7712. I was able to change to 1.588 but needed to yankey-doodle with the entry to get it to take the new number.

[@alldaypancakes7058]

hi paul McWhorter hope you are having a good day just curiosity can i use ardoino components like the joy stick or pushbotton with the raspberry pi microcontroler

[@buniyaminadewusi8593]

Thanks Alot Paul, I've been enjoying your Lessons alot, I'm having issues with my addins, If I click the c++ spur gear, the window will just disappear, and nothing happens, if I go and check the Create menu, It won't show spur gear. I restarted the software, and the computer. It still did not show anything.

[@Jim-hq1sj]

Hi Paul- I noticed my gear latches to the Z Y plane-as if standing up. How can I change it to the X Y plane-as if laying down. I noticed you do not select "create sketch" but go straight to "create gear" When I do that and select my parameters it goes straight to the Y Z plane instead of laying down on X Y plane-thanks

[@arlo4051]

Not sure if anyone else had this problem, but in addons for the spur gear for C it would not load but the python one would (using Windows 10 64)

[@mamadoubapassioninformatique]

Yes I had the same issue. The C+ version does not work, but the Python does. Also using Windows 10 64.

[@cbrombaugh]

I had the same problem Arlo. The Python version worked, the C++ version did nothing when I clicked on it.

[@jimwarb]

I had the same problem

[@rickbonari4493]

Yes, I had the exact same problem but my "C" drive where fusion 360 is located is very low on space so maybe the file space for c++ version was too large to load. I also used the python version. It works great

[@williammcdonald9086]

Yep, same for me. No joy with the C++ version but Python worked as described.

[@drzwithcrow6075]

Took about 30 goes to get the add-in to work. Well, maybe not 30 but certainly a great number and I didn't seem to do anything different when it decided to work. Just repeated and repeated, ad nauseum, then bingo.

[@cottagemail4066]

Oops ... At 29:52 the post is put in at 15.8mm instead of 14.8mm.

[@davidterry19and52]

i tried loading spur gear cc+ add on and it will not load. the python loaded just fine but when i do plugins as you are doing it is giving me an error of root fillet radius has to be below 1.9???.

[@KM-hp3br]

If nothing is happening after running c++ addin try using python one, worked for me. I have python insalled on PC maby that makes difference idk

[@DavidMiddleton]

Thanks for that! Worked.

[@garytann5408]

any lessons on blender

[@ronakvyas6595]

Sir, how about a "drone programming with python" series?

[@paulmcwhorter]

Drones are in fact flying blenders, and I want no part of a class where I teach how to make flying blenders, and one of you guys fly the blender into a neighbors face. No way am I going any where near that one.

[@davidterry19and52]

if i reduce or enlarge gears or nuts and bolts in my slicer should they still work?

[@paulmcwhorter]

I think you should edit in fusion 360, NOT resize in the slicer.

[@fransvanenschot3286]

Hi Paul, I have a problem with loading spur gears. When i hit the run button in add-in for spur gears nothing happens. when i hit the demo button. the demo is loading and appears into the create menu. do you now what is wrong? grtz Frans

[@fransvanenschot3286]

Problem solved Spur Gear is now in de create pulldown menu, but on the wrong place. It is in the section from box, cylinder, sphere etc. How can i move it to the last section?

[@stephennicholson2833]

@@fransvanenschot3286 I had the same issue. Didn't see it because I was looking where it was in Paul version.

[@ghal6993]

Hub for large gear should be 14.8 and not 15.8

[@DavidMiddleton]

Sort of Legend. I messed up a dimension as will be explained, but at the end of the day got it sorted out and had fun making the gears and the video! kzbin.info/www/bejne/i5fWcpira5WHd6M

Excellent!

Would love to critique what is missing in your lessons--not to say they are not informative, good job, but topics and things are missing, leaving many questions----Bill

[@paulmcwhorter]

Loved the print!

[@robertbrodine9841]

I was able to get this to work really well once I got the gears worked onto the posts :) kzbin.info/www/bejne/l17NlWmQe9mdias

[@paulmcwhorter]

LEGEND!

[@ghal6993]

Great lesson but a little annoying with so much repitition.

[@zorabixun]

Paul ..... i try to insert that Spur Gear script, but it is not in the Create, Solid menu and does not work no voila 🙂 haha i think that rubbish autodesk again removed something from the free version of Fusion 360, they are sick for every $$$ they lost from this free version, already almost empty of functionality I am sick of this autodesk idiots, the same when i login to that Windows rubbish .... In what rubbish world we are living, this psychopathic mafia surrounds us everywhere When we close f360 it takes few minutes to close, because autodesk steals our creativity to itself, even when we export to our local disk .... they also steal everything we have created, autodesk is just a thief of our creativity, but they limits the functionality of this f360, even if it is already almost empty application worth little like zero .... 🙂i will finished all your f360 tutorial, but after that i am switching back to my Linux and FreeCAD .... thanks for your time to make this interesting tut ....

[@thewrenchjockey4251]

I had trouble with the addon too, I had to restart, run the demo sample addon and then it let me run the python spur gear, then removed demo sample. seems like its just a glitch.
