Hey, great part! I put one of these as a free wheel on my robot. I also made a bracket to mount it to things. It's part #4902 ( http://www.thingiverse.com/thing:4902http://www.thingiverse.com/thi... ).

Happy making! :)

Bracket for 36mm Omniwheel

this was a great part to try printing. As you can see by my copy I had a hard time getting the wheel right. I think the clip over extrusion width setting in skeinforge would keep the wheel from bulging at one side. the plate and outer pieces turned out great. I can't wait to finish 2 more and make a omni-directional robot platform

Cliff, any plans on designing a mecanum wheel? :) Those are ridiculously expensive.

I am currently printing a set of mecanum wheels today. Its not makerbotable(?) but maybe someday.

Our school just got a 3D printer and I think everyone is afraid to use it. I was just thinking how great it would be to print a omniwheel since they are a unique but simple part. I'll try it on our commercial machine with ABS plastic and see how well it turns out and report.

Hmmm... You could do away with the axles completely if you could figure out a way to design-in ball-bearing tracks between the wheels and plates.

made a full wheel , original design!

and it works , good work cbiffle.

I just clipped the outside of the slots off so they were open C shapes. The top lugs all cracked but they hinged upwards and held on to the 3mm filament.

The rollers need quite a lot of work , cleaning and drilling the hole out to 3 and a bit mm.

The whole thing was then constructed with hot glue , filled the out side corners (x8) and put a bead around the middle t join the two halves.

a bit of cleaning and clipping and it was good to go.



Per your suggestion, the rollers now have 4mm centers and shouldn't require any drilling. (I've done some testing with polymer clay and 4mm shouldn't be too much play, while allowing for some shrinkage.)

Very nice. I'll fold your mods into the design; I was already redesigning it to use crescent-shaped axle holders, so it's great that they work. I wonder if the Tower script in skeinforge could improve the quality of your roller batch? I haven't tried it myself...

O' your biffleness:

The wheel prints out OK , needs some more meat on it. I would make the slots a bit smaller as the outer edge just kind of splodges.

have a look



p.s. do you have more info on your DPR?

Oh, re: DPR (missed that the first time) -- he still chases balls around my apartment. I'm frustrated with his current chassis, which is why I'm gradually designing all of the parts I'd need to replace it. My wife refers to it as "upgrading the kids." :-)

I'm actually redesigning it to exploit that! The axles don't need to be in holes, you can simply glue them in place. If you use some 3mm filament as axles, any plastic glue or CA cement should do nicely.

Glad you tried it!

Good work cbiffle, I did a lot of blending and dreaming before my makerbot arrived.

Keep it up and make sure you have a few simple ones ready to print for when your Cupcake is ready to go.

Oh, believe me, this isn't first in my queue. :-) Once I get cubes and cylinders printing straight I'll verify this one.

Nice! I'll try to print this one for sure!
