I saw the youtube video where the guy prints a 3d printed bicycle<http://youtu.be/hmxjLpu2BvY>and rides it without any assembly. I want to do that with my Makerbot Replicator !!! (so cool). However, I am not an engineer and don't know how to draw a one way ball bearing. I saw a ball bearing (2 way) on thingiverse that prints with water soluble support material on a dual extrusion Replicator, but no one way ball bearing.
Can someone please (pretty please) post a 2 way ball bearing on Thingiverse so that I could use that to create my bicycle? I will accredit you with eternal thingiPraise when I post my bicycle as a derivative on online. I'll even send you a free bicycle if you'd like.
Yeah, I know, the wheels will have to be kinda small.. and since the Replicator is much smaller than a million dollar 3d printer, I'll probably have to do a bit of assembly but, hey, as long as it works!
I don't think the 3D printed bike in the video used any one way bearings that I'm aware of. It appeared to me like it was a direct drive thing so that when the bike is moving the pedals are constantly moving too. Maybe I'm misunderstanding what you are asking for.
Do you own a replicator? Because I don't think you understand how small the build platform is.
I've pondered making a printed bike before and in my mind you could make printed joints and printed gears and printed pedals, but using PVC piping or maybe something more sturdy for the frame. But it's not the sort of task I've been particularly up for, busy as I am with more reasonable projects.

I have a replicator. Frame will be printed and assembled like legos with glue. Wheel s will be small. So, anyone can cad design in stl a one way ball bearing? I will do the rest.

I admire your goal... and I eagerly anticipate the day when it is in fact a
reasonable option to print bicycles on home 3D printers. That's gonna be
awesome. Right now, though, with the Replicator as your primary tool, it's
a real challenge. Your difficulties will go far beyond your need to have a
one way ball bearing.
Should you choose to accept this challenge - and it could be a really great
project if you do - I think it will be best if you take this opportunity to
grab one of the CAD packages out there and learn to drive it. You clearly
have a lot of exciting ideas, neat images in your head. Your personal CAD
proficiency will always either limit or empower your 3D printing efforts,
at least until you're able to hire someone to do your design work for you.
Once you've gotten started working in a CAD package, I'm sure this
community will do whatever we can to answer questions you come across, and
try to help you get that bike rolling - or whatever else you choose to
design.

sorry, i didn't know that i posted so many duplicate replies. my iphone did not say that it posted successfully, so i assumed that the posting failed.
i already know how to use a cad software. i use netfabb and tinkercad. netfabb is professional grade cad software. however, i have no earthly idea what a one way ball bearing is other than that it only rolls one way. seems like magick to me.
will a super genius please help with this? thanks.

No, the efficiency of that ratchet wrench would be horrible because it is not a one way bearing. It is a leaf spring design. Efiiciency needs to be a concern because it has to roll as a bicycle. This wouldn't roll.
I could design it so that you'd insert a metal bearing you buy elsewhere into the bicycle. However, that wouldn't be a proof of concept of a ENTIRELY 3d printed bicycle. I even want to wheels to be of a 3d printed design kinda like the "big wheels" toy tricycles with ABS tires, no rubber air inflated tires. I want the ENTIRE bicycle to be 3d printed. The youtube video had a bicycle with inflated tires and rubber handles. I want to do a one-upmanship on them and do a 100% 3d printed bicycle.
I think a crankshaft design would be more sturdy for ABS than an ABS chain. Then, lego-like construction of the frame in pieces. It will look weird with tiny wheels because it has to fit on the replicator's tiny HBP, but at least it is possible. With the TOM or cupcake, their diminutive sizes make it impossible.

It seems like the one way ball bearing would need to be a very exact tolerances, not possible with the makerbot replicator because it needs to be sealed in grease? Or else it won't work. It cannot be a simple open design ball bearing like the 2 way ball bearing?
Maybe it can work only if the ball bearing is oversized and a whole lotta grease is thrown on it? you'll get greasy just looking at it?:
any engineers wanna take a stab at it? student exercise? I'll buy you an in and out burgers meal if you're in Dallas. or a pack of domestic beer if you're over 21.

I assume you'll be making the wheel solid, as I can't see spokes working
out well in this context. In that case, remember that just because the
hub on a regular bike is small doesn't mean yours can't be larger - it
could take up the entire interior of the wheel. Then you could scale
everything up enough that the tolerances are acceptable.

Also, the EADS bike was made with sintered nylon powder. I doubt that FDM with our usual materials will have anywhere near the strength to make a usable bike.
