90 degree PTFE tube guide.

Together with the guide, I used https://www.crealitycloud.com/model-detail/657e19d8937557724252afab, reducing the height to 50%

I recommend printing this in ABS or ASA.

I initially printed this in PLA, but it didn't stand up to the test of printing with a closed chamber. Ultimately, I printed it from ABS and so far it works.
