Filament Rack Extender

Filament Rack Shelf Extenders for 9-Tier Modular 3D Printer Filament Storage RackI designed this storage upgrade to complement the popular 9-Tier Modular 3D Printer Filament Storage Rack. While the original rack works well for full-size spools, it has one major limitation: you can’t efficiently store small spools next to large ones, which leads to wasted space.These rack shelf extenders solve that problem by adding modular dividers that let you stack and organize smaller filament spools on the same row as larger ones.Easy to install – simply clip the extenders onto the rack sections designed for small spools.Space efficient – each extender adds up to 7 extra spool slots per row, maximizing every inch of storage.Scalable solution – when fully installed, you can expand your rack to hold up to 63 additional spools without taking up extra floor space.Customizable – works with a variety of spool sizes (250g, 500g, 1kg, and even odd-sized specialty spools).The model comes in 4 printable mode
