Original Design: https://www.printables.com/model/215950-cleat-for-ryobi-link
All dimensions are like for like with the original design linked above. I simply recreated SemaphoreSlim's great design and uploaded a .STEP file which can be downloaded and edited to be anything you need.
Make sure to upload any of your designs as a remix of the original file so others can make use of them!
Refer back to the original model.
