Nema 17 Double Sheer E2 Encoder Mounts

This is for mounting an E2 US Digital Encoder to a nema 17 with a long shaft in a double sheer mount.  I am using this with luke labratories long boi ldo 2504 ( https://lukeslabonline.com/products/longboi-ldo-nema-17-motor-high-temp-ldo-42sth48-2504ahs55 ) would work with other versions as well. I am using cnc kitchen/ ruthex inserts https://cnckitchen.store/products/gewindeeinsatz-threaded-insert-m3-standard-100-stk-pcs
This is needed because the minimum boss diameter is smaller than many other options and space is tight.  Use a 685 sized ball bearing I am using some uxcell ones here but I had to throw out about ⅔ of them so please feel free to find something from a different manufacturer/supplier these work but they're not ideal ( https://www.amazon.com/gp/product/B0819886SG )

Update:
Added printed thread version (use a lower layer height, maybe chase with m3 tap after printing)
