Hey all - I have the 40W laser head for the Snapmaker2. I lost the threaded insert for the air assist tubing, and can’t find it on the store or the specs (m5? m6? 6mm?). Anyone happen to know what these are? Cheers!

Simply write to support, attach a photo of the 40W laser, and mark the area with the missing part. Then ask your question.

Or

Here is a picture with text: What it is (outlined in green) and its size (underlined in green).

You can order the replacement part yourself using this information, which is usually cheaper and faster to deliver!

You can also find the push-in fitting on Amazon!!
