Replacement grommet for Troy Bilt chipper clutch

For a few years I've been annoyed by the rattling of the clutch handle on my old 10hp Troy Bilt chipper shredder where a failed plastic grommet was supposed to be.  Once I began thinking about purchasing a 3d printer, it quickly popped back onto my radar for a simple problem to solve.  I finally needed to use the chipper this morning, so before starting I took the opportunity to measure it up and model a solution.  I printed in PETG so that it can be bent around the 9.5mm rod that it will support without breaking.  I've included a v-slot opposite the flange split to allow the part to more easily stretch around the shaft for installation

The Version 1 gcode file uses close to the standard MK4 IS profile for Generic PETG, with the only changes being 100% infill with top/infill/bottom layers all being set to Concentric.

The Version 2 bgcode file is sliced for my now upgraded MK4S and TPU.  I've started with the standard FLEX profile and changed the top/infill/bottom layers to concentric, and maximum volumetric speed set at 3 cubic mm/sec.  This dimensionally adjusted version is easier to install (due to flexible TPU), fits more snugly, and completely eliminates the rattling noise while running the chipper.  I expect it will also be more durable long term.  I first tried printing the V1 part in TPU, but it did not fit snugly enough.  The flexibility of TPU allows the dimensions to be expanded to tighten the entire interface while still installing easier than the PETG version.  

I also have a fully parametric version of this grommet design, making it adaptable to any use.  See the link below.
