Remix of the Creality CFS tensioner using POM wheels by 'vgergo' which is a remix of the model from the design by 'mdalacu'.

I really like this modification for the CFS keeping the spools from jumping up when retracting filament. My only problem was that vertical lips of the base easily snap off when you try to insert the original bumpers. So I redesigned the vertical lips to be stronger while still being able to flex so you can insert the bumper. 

Also I changed the vertical holes so that they can be printed without supports using a bridge before the hole. 

The rest of the files are unchanged.

Print settings:
Use 3 walls, 0,2 mm layer height and normal infill percentage with your favorite pattern.

Refer to the original for assembly instructions.
