Ankermake M5 cable support

This is an evolution of a previous design I had for a printable underbed cable support to replace the stretchy band that the printer comes with by default. I also liked the suggestion on the M5 Discord channel to incorporate PEI guides to help align the build surface, so I have several different versions of the design:A simple underbed cable support without PEI guides.A combined cable support and PEI guides.A third option of the underbed cable support with removable/adjustable PEI guides.Option 1 and 2 are pretty self-explanatory. Option 3. I came up with the third option as I printed the test piece cable supports in eSun PLA+ which handles a 60 degree bed temperature well. I did some prints at 70 degrees and the cable support was unaffected. But at higher temperatures I expect the PLA+ material will soften. The third option allows you to print the support assembly in PLA and the cups that touch the bed in a higher temperature plastic such as PETG or ABS. I am now running an all ABS op
