Ninja Blender Replacement Gear for Pitcher

I have an old Ninja blender model 780. The pitcher has a gear inside that I stripped while blending up old 3d prints in preparation for melting into skull molds. I found a gear at https://www.thingiverse.com/thing:6497391/ which was too large and didn't have the correct interior shape. So I scaled it and added the interior piece. I made the tolerance quite tight, requiring a bit of heat to press into place (I then removed it, applied superglue, and pressed it back). Works great!
