Modular Filament Spool Holders

These are to hold multiple rolls of filament. They hold most 1kg spools with the grooves being able to hold spools that are between 62mm and 70mm in width. The inner rectangle can secure many 250-750g spools of filament as well.

There are two sets of models. One that requires you to print the alignment pins, and another that uses a ~15mm piece of filament as the alignment pin. These are intended to have multiple printed and modularized, there is a left (alignment holes on the right side), middle (alignment holes on both sides), and right (alignment holes on the left side).
