This spool holder from Print BIG is specially designed for the RatRig V-Core 4 to allow larger spools to be used within the installation space and not be limited to most 1kg rolls, as is the case with the RatRig holder.
This is particularly important for printers with enclosures.

Although the spool holder was designed specifically for the RatRig V-Core 4, it can also be used universally. All filament rolls can be used.
The spool holder can also be used on both sides. The PTFE connection can be easily attached to the other side.

The special design allows the filament to unroll smoothly despite the limited space.

The spool holder consists of several parts so that it can still be assembled.
You can either purchase the entire spool holder, fully assembled and ready to use with all parts, or just the hardware parts. The printed parts can be printed yourself at the following link:
