Công cụ canh chỉnh bộ đệm (Buffer) cho máy in Bambu A1

My A1 had a problem on a pretty regular basis. 

The PTFE tube going into the top of the buffer for the AMS would start leaning to one side and the buffer tube would get bound up causing feeding errors through the buffer to the nozzle. 

So I designed this very simple buffer alignment tool to make sure that the PTFE stays straight up and down in respect to the buffer. I hope you find it useful!
