K1 Spool Holder Stand - fix version

Fixed version of spool holder for creality k1. The original version is not centered on the support, and it protrudes. This remix corrects the centering and refines the support for tight spaces. There is also a non-beveled edge on the foot, also corrected. I also provide a narrower version for even tighter spaces, compatible with my remix of the bearing spool holder.
