Well, I finally impressed the wife.
Our shower head (one of the fancy ones with a hose) was leaking. I took it apart and discovered over-tightening it will cause an internal part to crack/split (ring that holds an o-ring in place.) Who’d have thought! (The replacement models are being marketed as “unbreakable” on their website.)
I figured I could make a replacement piece out of HDPE that I have and a simple layout of a 1.25" ring that snaps in. It worked like a charm! First try even.
Wife was happy and I showed of the usefulness of the x-carve. Yay me!
