Remixed Printrbot Simple Metal "Finger Flobber

This is a remix of the original "Finger Flobber" for the Printrbot Metal Simple by motorbikemikexb9. While I truly appreciate his design, I did not wish to remove the tensioner screw in order to install this little doodad so I edited the stl to include open channels on either side that allow the part to simply slide over the adjuster arm.

I hope others find this useful, as well. And thanks to motorbikemike for the original design!
