Perhaps something similar to the following:

I've had prior experience and success printing a custom electrochemical cell using Formlabs resin (in my case clear resin), which has relatively good chemical compatibility. I believe I was using NaOH, and I ran some of my own "print a cube, let it sit in solution for X amount of time" tests and saw negligible mass differences.

The intention is to use this with KOH at a relatively high concentration for extended periods of time.

Aside: Here are some examples of custom ones that I came across

@MiceeNS, there is a water jacket that is used for keeping the internal container at a constant temperature. Five ports are required on the lid. There needs to be some kind of gasket between the lid and the cell.

In terms of parametrization, the size of each whole and the overall dimensions of the cell (i.e., internal volume) are the main ones.

Internal volume likely somewhere between 200 mL and 1L
