tldr; My StellarSan caps broke and I printed new ones.
I know this is no strictly the right thread but I thought I would add my 2c here as I lost both my StellarSan caps today (
RIP plastic caps) and its also likely the first place someone will come to complain and look for a solution.
Most likely I am also going to get flamed for this so let me start by saying this was a proof of concept and I may change to a more suitable material before I post the stl. If you want to the stl let me know and I will supply what I got. Caveat Emptor as there are no guarantees this will keep on working. For now I will see if they split like the orginals, if they are still fine after a week I will update my post with a link to the file.
Anyways are is a pic. Printed real rough and quick as a proof of concept. They seemed to seal without the paper discs but I migrated them across anyways.
