Modular Shelf & Filament Holder

Modular Shelf & Filament Holder – Dual Surface System with Rod Mounts (Ø20 / Ø23 / Ø25 mm) This modular shelf system is designed to provide two different storage surfaces in one compact design. The upper section functions as a classic flat shelf, while the lower section allows you to mount tubes or rods with diameters Ø20, Ø23, or Ø25 mm, creating a practical holder for filament spools or other round objects.The design is optimized for strength and stability. I tested the shelf by loading it with 20+ kg, and it held without any issues.For mounting, I used my custom expandable wall plugs, which you can also find on my MakerWorld profile (see link). These plugs ensure excellent grip and reliable anchoring even under higher loads.This system is ideal for organizing your 3D printing workspace, storing filament spools, and creating a clean, functional setup. 🛠️ FeaturesDual-purpose design: top shelf + bottom rod storageCompatible rod sizes: Ø20 mm, Ø23 mm, Ø25 mmDesigned for filament spool
