3/8in Compression Cap Cover

We started demolition on our bathroom for a remodel after the kids went to bed and found that one of our sink valves had gone out and was dripping. It's after midnight, the stores are closed.

So... I looked up the schematics on a cap, modeled it in Fusion, and sent it.

Probably not great for long-term use, but it's held up for the last half hour with nary a drop!

3MF file is built for Bambu Studio 1.7 and has a height modifier to print the threaded part at 0.08mm. Took about 20 minutes to print. Use a strong material, PLA+/PETG.
