Versatile Spool Holder for 2020 extrusion frames

thingiverse

This is a versatile spool holder for 2020 or 2040 extrusion frames that offers flexibility and customization options. It can be adapted to fit [Prusa i3 MK2/MK3 style frames](https://www.thingiverse.com/thing:2797675) as well, giving users even more versatility. The spool holder can be placed on top of the frame, secured with an M3 bolt if desired, thanks to a conveniently located hole. Users have several options for rods, including 8mm, 10mm, and 12mm diameter smooth or threaded rods. For smooth rods, designs like alexrosa's [3D Print Spool Holder Filament Support](https://www.thingiverse.com/thing:2112075) or boksbox's [hub adapter](https://www.thingiverse.com/thing:1481725) can be used for additional support and functionality. Those who prefer a hub with bearings can print designs like butchja's [Universal Filament Spool Holder](https://www.thingiverse.com/thing:2070272) and attach it to a threaded rod. The spool holder can be configured as either a single or double filament holder, making it suitable for various printing needs. Additionally, I have included clips for smooth rods in each diameter size, providing users with even more options for customization. As requested, I have also added shorter versions of each item, offering users an alternative that is easier to print and assemble.
