兄弟厉害,2016年就玩这

can you please make a 60mm mecanum wheel and upload the files please.i want 60mm mecanum wheels for my college project.

Hi thanks for sharing this awesome idea. I loved it. I have some questions:
1- How did you connect the wheels to the motors?
2- And how the wheels hold the rollers? I meant do the pins not falling?

I also had the same question. you can easily melt the model to hold the pins.
put the pin and the roller inside the wheels and melt the model with the solder.

Could you upload the dwg files or something of that kind?
These STL files can't be edited . Thanks in advance.

Hey, it doesn't look like this has a hole for a D-shaft, however the motor you use has a D-shaft. Is the friction enough to fix the wheel to the motor shaft? If possible, can you upload design files so I can modify it? Thanks

Will be that wheels compatible with a 3 wheels omnidirectional robot as that one http://www.thingiverse.com/thing:1276446 ??. I see that you have wheels for right and for left sides, in a 3 wheels robot the configurations is different, isn't it? Thanks!

Although mechanum and Omni wheels both have rollers their application is charectoristicly different and mechanum wheels always needs to used in pairs of 4.

How are you "locking" the pins into place?

I'm using super glue, but if you're redrilling and use the right drill bit, you can get a friction fit. I've found that a size 70 is just about right

Forgive me if i'm being dense, but with a symmetrical hub couldn't you have just made one wheel model? Is it a design element or is there a mechanical element that necessitated a left and right wheel?

Notice if you flip the hub arround the rollers are still tilted the same direction. Mechanum requires that they​ be in opposite pairs so that their force vectors can cancel against each other.

Hi,
Thanks so much for sharing this great design again. I have just printed the wheel body with FlashForge Creator. The top part over hang is too rough though. Cannot fit rollors for sure. I printed with PLA, 210 degree C for extruder, 60 c for platform. Travel speed = 60 mm/s, Z-axis Travel = 23 mm/s. Roller uses the same settings too. The hole is filled though. Any helps, please? Thanks.

did you try to lower the layer height? I set the layer height to 0.1mm and it made a fine hole.

Thanks for the mention,actually I had plans to make smaller wheels and use N20 motors a couple of years back... and even just this year bought the same chips etc as you to continue the project but have just been too busy :)

@vurpo using watch spring bars is very finicky, very very annoying actually.

Alternatively to dressmaking pins, you can use 20mm watch springbars as axles for the rollers.

What are the shaft dimensions of the motors. I'm trying to make sure that what I buy is compatible with this model.

Please upload the openscad file, too...

Beautiful! Could you please scale it up a bit? Something like 66mm diameter or around that would be great. Thanks!

I'm learning OpenSCAD recently so may be a parametirc one? Give me some time.

That would be the greatest! Thanks!

what about all parts for this rover? pleas

I'm working on an improved cart body. It may take a few days through.

You misspelled the title.

@ mariustcaci:
that's right, but you haven't found the right word: Mecanum wheel. If the title can be changed, the search function of the website will find it later.
@ Jonah:
thanks. Great work, good instructions. My printer is printing it right now.

Thanks bro!! Sorry for my fat finger.
Let me know how your prints works.
