Colliflower Kapex Replacement Zero Clearance Insert Block

I own The Cube for Kapex (Zero-Clearance Fence) from Jack Colliflower. (https://www.colliflower-zci.com/store/colliflower-zero-clearance-fence-for-kapex) It's an ingenious design and works great. It has also improved my dust collection. I've made so many cuts that I needed to replace it. I designed this insert. It provides a good friction fit and fits perfectly. I received permission from Jack Colliflower to post this so others could 3D print their own replacements.
