Improved Blender Base Replacement for Hamilton Beach Screw-On Bottom Blade Hold

3D Printed Improved Blender Base Replacement for (Hamilton Beach)

Over time the screw-on base ring ends up cracking in one of two ways: either it splits vertically at the top edge, or it splits horizontally where the blender jar bottoms out against inside of the ring. I've also had the threads start skipping because of minimal thread engagement with the jar.

This design fixes all three problems. It adds a reinforcing ring at the top to prevent vertical cracks at the top edge. The added height also provides more thread engagement with the jar. And it eliminates 8 of the 12 vertical notches (only 4 are needed) to provide more material in the area prone to horizontal cracks.

Fits most Hamilton Beach blenders.
