Filament Holder

The spool holder is heavily inspired by this spool holder https://www.thingiverse.com/thing:1185076. Its design is from scratch, beefed up, and uses an M8 screw to hold the rollers. The main reason for this design is that after a year of use with the Universal Filament Holder, the print-in-place holder for the rollers broke. Additionally, I changed all the screws to be M3x12mm. One thing to consider is that if you don't want to use many M3 screws, you can use super glue or a 3D pen to fuse side 1 and side 2 to the base. For side 3, I recommend only using screws to attach it to the base in case you need to do any maintenance. In the picture, as you may notice, I had to sand my rollers because of tolerance; this has been fixed.

Everything added to the build plate takes about 12 hours on my Ender 3v2 with the stock setting of prusaslicer.
