For the case https://www.printables.com/model/345083-rugged-multipart-pinecilts100ts80-case-v2. I tested the lid with TS100_Pinecil Top Large A.3mf
, but it should work with other A variants, since they all appear to have a 33x34mm square container.
The lid was printed in 95A TPU. You may be able to get a better seal using softer TPU and slightly increasing the lid X/Y dimensions.
My pinecil case was printed in PLA+, and I waterproofed the flux container with silicone. I'm not sure how the PLA it will age in contact with the flux. Maybe PETG would be better suited since it is waterproof from the start.
My PLA case was printed on 2023-05-13. I will update this page if I have any issue.
Update 2023-09: still no issues between PLA and flux
