This is a work in progress. The X position of the idler pulley needs work, as well as the mounting hole size.
I was able to print an earlier version of this and alter it with hand tools. I wont be reprinting for later versions because mine works as-is.
Feel free to manipulate the file and re-upload or pass it on to me for editing this "Thing." Please give credit if you utilize this piece in any future versions/iterations.
I used Autodesk Fusion 360 to design the part. I am new to the program and CAD; please forgive the VERY unorganized design. A downloadable link to the fusion 360 part: https://a360.co/2EZ9ubP

I suspect more top/bottom/side layers would negate the need for 100% infill. Use your own experience as guidance.
I used PLA because that is what I have. PETG or ABS would likely work perfectly fine.
This mount is for the 40x40 extrusion used on the Ender 3 Pro.
