When I got my Anycubic Vyper I really liked the printer (I don't anymore, since I have X1C :D). The one thing that I despised was the filament holder on the side, since it required extra space around the printer.
So I have created solution for this.
This holder should work on all printers of similiar construction. The top part can be rotated 90 degres to acomodate for direct drive printers.

For this build you are gonna need the following:
- 2x ball bearings (608z) 8x22x7mm
- 8x M3 screw
- 8x M3 nut
- 2x M4 screw
- 2x M4 square nut
- 1x M8 threaded rod (120mm)
