Bottle roller help Answered

So i have bottles ranging from 60ml to 500ml that i'd like to make a roller for mixing.
The issue is that the only mixers like this are in the $1,000 and up range, it's honestly criminal. see here http://amzn.to/2h6gHYG
Anyone have ideas for parts to make a super cheap version of one of these?

Steel pipe, press bearings in and use some nice bolts to mount.
To drive it use a belt on the end of one of the rollers.
Old inkjet printers should supply you with the motor and belt part, skateboard bearings cost under 10 bucks for a pack of 10...

Here's currently what i ended up buying, on bit of a budget.
so the bearings http://amzn.to/2h9hXgd will fit into a pvc pipe i have, if i heat up then ends and press it in.
Since the center hole is 12mm i got this to fit into it and attach it to a wooden frame http://amzn.to/2h6LwMu
then last of all i got a 12mm drillbit so i can run the holes into the wooden frame http://amzn.to/2gFpjo0

This is currently the pipe i have laying around, it's not thick, but i think if i make them short enough just to fit the largest bottle, the amount of sag will be very minimal. https://www.lowes.com/pd/Charlotte-Pipe-3-4-in-x-1...
Then later down the road, i can upgrade to some stainless pipe.

I'm going to add is some nonslip shelf liner around the pipe

for rotation i have this from many years back, it has it's own on off wireless switch now. http://www.allelectronics.com/item/dcm-351/24-vdc-...
The outside ring has a rubber round thing on it, so it'll get good traction for turning.

will be nice to finally have this up and running.

Grab one of those R/C car toys - with the good rubber wheels, flip it upside down and gut it to move one set of wheels closer in to support the bottle. Don't know what speed you need to run it at but it would be simple to have an arduino control it for speed and duration. Good luck.
