Label signs and plug-in and printable axis

The signs are for:
- 80
- 120
- 180
- 240
- 320
- 400
- 600
Sandpaper preconfigured, but can be customized in BambuStudio.

The axis consists of three different parts, top and bottom and the middle parts, which must be printed as many times as there are sandpaper holders between the first and last.

The remix contains the pre-labeled signs in .3mf format from BambuStudio. I also designed a pluggable and printable axis so that you don't need the high bar.
