[Snapmaker] Go-Pro filament guide/mount v1

Although originally designed for my Tool Holder v2 this GoPro spool/filament guide works with all GoPro connectors and can be adapted. For the Snapmaker in particular, I noticed it is not quite long enough for the average 1KG spool of filament.

I originally used PETG for the print displayed in the images above, however, other materials should be possible :)
