Resized HEX Spool Holder with PTFE tube guide for spools with smaller center diameter

Having the PTFE guide for the spoolholder was a great idea but after printing the original remixed version by Chiu Kang, I found that it didn't fit any of my spools. I liked the design so much I decided to remix it again for smaller spools, retaining the PTFE tube guide.

This is a resizing of the main arm to fit smaller spools such as the original Bambu spools, Overture or GST3D spools that would not fit the original model.
