PVC downtube carrier For Bubble Bucket

I designed this thing to eliminate the aluminum extrusions in the bubble bucket assembly design, and use something I had laying around - 1.5" PVC pipe. Print in a pair, and this PVC clamp will hug the lip on a standard 5 gallon bucket from lowes (or home depot i assume) and clamp around a vertical PVC pipe with 1/4-20 bolts to suspend the bubble belt assembly. In the vertical PVC pipe, you can easily cut a slot for the bubble bucket gear on bottom, and mount the drive motor on the top.

Modeled in Inches so scale up by 25.4

UPDATED: Added motor mount with radius to fit PVC downtube

Update2: Added chamfers to drive and idler gears to prevent chain from walking and jamming. Much more reliable now.
Motor drive gear hole was slightly off center and small for my shaft coupler so I made it larger (.26" i think??) and re-centered.
