External PTFE Spool Riser for Bambu Lab A1

This is an adaptation to raise the position of the PTFE tube guide of the Bambu Lab A1 external spool holder and allow more clearance. When I used my A1 printer with the external spool (without AMS), I always had some difficulty in placing and removing the spool from the external support, without hitting the PTFE support, due to lack of free space. and I noticed that some of the spools were very close to the support of the ptfe tube guide. Some even touched the ptfe support compromising its rotation. Especially, after upgrading the external spool holder with a low-friction mount, the spools would get too close and/or even touch the PTFE tube holder, thus leaving little space for the spool to rotate freely effortlessly. This situation was compromising all the functionality and interest of placing a low-friction support. So, in order not to give up on the low friction support, and seeing that there were not many options available to my liking to print, I decided to design my own support,
