Thanks! Its exciting to be able to have an encoder directly on a CIM, but without a shaft extension it might be tricky to put to use in this fashion. The encoder's instruction recommends removing the actual encoder no more then three times, and it is also very robust. But you are right, It take extra time to replace the whole unit if one part does fail.

We machined the part on a Centroid Conversion CNC, and added the mounting holes later on a manual mill.

The Counter sunk holes are actually mistakes The zero was a little off when it was first machined. The counter sunk allen-head screws are securing it to the CIM, and the two tapped holes are the same bolt pattern as the CIM, 10-24 to be used similarly for mounting.
