Show me your Universal Joints

I make them and I’m in Sydney. Takes a few weeks to have them fabricated in a factory in China. Will PM you.

Do you still make them? Can I order?

Please PM me
Cheers

Great job. I used car parts. They work great in my project. But I had to modify the grinder

Hi, yes you can order.
They are custom CNC machined from 7075 aluminium, and I can generally modify the design, finish, and anodising colour to spec. each individual Aluminium joint (2 pieces of aluminium) costs $100usd plus shipping when purchasing a set of 6 or 12 joints. Manufacture time s approximately 3-4 weeks.

Thank you. I found a cheaper solution. If it works fine, I'm gonna stick to it.

I designed them in Tinkercad and 3d printed in carbon fiber pla with my ender 3. Some of the top peices are in PETG cuz I ran out of cf-pla and petg is half the price lol

I can’t comment on the design as the photos are so dark and blurry.
Are you confident 3D printing will take the loads required?

I think so I made them out of carbon fiber and petg I believe a carbon fiber PLA and the top sections of the mounts are out of petg because I ran on a carbon fiber so yes I think so they are extremely strong the petg I'm a little worried about but the carbon fiber absolutely not I'm sure that's going to hold. And I won't lie I'm a little concerned I am that's why the the top piece of the mounts are they go through they go around the the cross bearing through the mount and into a steel plate that mounts to another steel plate that's connected to the actuator so the bottoms are made out of carbon fiber which they can be they can go around this the cross bearing through the mount and then into the metal of my base when bolted so it can be made very strong I believe I'm hoping they're going to hold

How much

Very nice work.
Would it be possible for you to share your .STL files with me?

Awesome 3D print quality man how do you get it to look so nice and so perfect

I really like this joint would you please share your STL files with me

Sure!

All parts print without supports. PETG @285°C

Let me know, if you need STLs. And be sure to use actual shoulderbolts, not just ordinary hex screws.



I will be travelling (Vancouver and Portland) for the rest of August, so I might take a few days to answer.

Hey man thank you very much I appreciate the hell out of that man thank you. Yes sto files would be easier because I don't have Fusion 360 at the moment so actually it's some STL files would be better for me if you could that would be great

Here are the STLs, but you should definitely get Fusion360 (it's free) to understand and adapt the design. 3D printing allows for a highly integrated design, meaning you can pack a bunch of functions into the same part. On the other hand you will then get a part that is specific to your needs only.



In this case here, you should adapt the design to match the diameter of your rods, the method of mounting them to the rods, the dimensions of the bearings you want to use, the dimension of the thread (metric or imperial?). And also, if your actuators are not internally constrained, you can omit the axial bearing on the single-sided design alltogether.

Mechanical design is a solution to a problem. Make sure that the solution matches the problem! Or even better: Tailor the solution to your problem for best results

Thank you so much bro. You say Fusion360 is free huh?
I coulda swore it was a paid software...
Thank for everything.
Oh you mentioned my actuators..
Heres some pics of the ones a made

It is free for hobby use. The feature set of the free license is way enough.

And if you work anywhere in education you can get an educational license to get a full-on version, but you won't need it.

Thank you so much actually you know in CURA you can just download the whole STL file and it comes out as one completed universal joint right, but then if you right click and choose a break into pieces, it disassembles the whole universal joint for you and you can just delete what you don't want to print. like the nuts and bolts that u want to be metal. it's pretty neat.
I did download FUSION360 tho.

so yeah I was able to get some printed. man these universal joints these things are nice man they are built tough I really really like the universal joints I think you did an excellent job
