Multiboard Filament Spool Rack Mini - Updated

This is an updated version of my Multiboard Filament Spool Rack Mini. This latest version uses the Large-threaded locking bolts. A modular, efficient solution for storing multiple filament spools using your existing Multiboard tile system and a standard closet rod or dowel.This is a redesigned version of my original Multiboard Filament Spool Rack/Shelf, rebuilt from the ground up for wider printer compatibility—including the Bambu A1 Mini. It prints about 30% faster, uses 25% less filament, and requires only one support rod (instead of two). The main bracket is designed for a 1⅜″ (35mm) closet rod, but included spacer adapters make it compatible with 1¼″ (32mm) and various metric dowel sizes.Bracket RequirementsThe system requires at least 2 brackets, spaced apart to support the rod and spools. For each bracket, the following Multiboard parts are required:(1) Heavy Weight-Bearing Hook Snaps(1) Locking Bolt (Supported)<
