It is a fine pitch tread, so just slightly too much play and it might collapse under load, it is good if you test this before installing it in the printer.

The I2K-version is thinner, only use that one if you actually have an I2K-washer installed.
Please note that this is a prototype!
I might spend some more time on this and upload the files somewhere else in the future if I think the designs works good enough.
