Gear for Kenwood HB723 or HDP 408WH blender

A vital gear inside my Kenwood HB723 blender broke down, prompting me to design a replacement part using PETG material. After rigorous testing over several weeks, I'm confident in its performance. You can witness the thorough examination in this video: https://youtu.be/hD8TeM7rfVg I hypothesize that the same design was employed for the newer HDP 408WH blender model. To access the top part of the blender, a flat screwdriver and considerable force are required. Unfortunately, both components are stuck together at various points due to gluing or melting. To assemble it, I used a Dremel tool and PLA material to bond the two parts in several areas, as epoxy glue proved ineffective. Update: Five months have passed since the repair: After five months of use, my Kenwood HB723 blender finally failed when my wife was mixing grains. Notably, the gears showed no signs of wear; instead, the gear melted due to excessive heat at the shaft, causing it to bond to the shaft.
