Although the model is simple, I put a lot of effort into it, printing and modifying it six times before finally settling on this material-saving, time-saving, and practical version. I hope for your support, and I will continue to design simple and practical models
Only 20g of PLA is needed for bookshelf filament storage, comes with 2.1mm filament end fixing holes (balancing print quality and filament storage), modular design!!!
2026-03-29 Update: Since many cabinets cannot be arranged with full-width placement on both sides, a side piece with a side stopper has been added, with a width of 70mm (including a 2mm thick side stopper), which can effectively prevent filament spools from sliding off the side.
I have a few empty regular bookshelves, which are perfect for arranging filament spools side by side horizontally. But I believe everyone has encountered this awkward situation: when the cabinet shakes, the filament spools 'run away' and roll onto the floor. I referred to many existing stopper designs, most of which require additional rollers and screws, which are not only time-consuming and material-intensive, but also do not meet my need for 'maximizing the use of idle space'. So, I designed this 'three-section modular stopper'
- Extreme Material Saving (The 20g Magic): The entire model has undergone multiple rounds of topological optimization. If you print with PLA, the total weight is only a little over 20g. This not only saves money but also greatly reduces printing time
- Modular Self-Locking Connection: The model is divided into three parts: Center and Side pieces. They come with connecting slots, allowing you to infinitely string them together and adjust the number of stoppers according to your cabinet's width
- Universal Compatibility (Wider & Open Slot): The slots are designed to be wider and open on both sides. I have tested most mainstream 1kg filament spools on the market (including original Bambu Spool, eSun, PLA+, etc.), and they all fit perfectly
- 2.1mm Filament Thread Storage Hole: This is a small but delightful design. A 2.1mm diameter hole has been added to the side of the stopper. Unused filament ends can be easily inserted and secured, eliminating the need for filament clips
- Material: PLA is sturdy enough, PETG offers better toughness
- Wall Loops: Default setting: 3 walls. You can appropriately increase the number of walls, which helps improve the durability of the storage holes
- Infill: 15%-20%, spiral infill recommended
- Orientation: The default 3mf file has an optimized print orientation for perfect printing without supports. If smoother slot curves are desired, you can adjust the print orientation (but this will require supports, which have not been tested yet)
- Installation: First, insert and lock two side pieces into the center piece to form a basic filament holder. You can expand it by adding more center pieces as needed
- Plate 1: Side A, Plate 2: Side B, Plate 3: Center (Adjust quantities according to your actual needs, single width is 68mm) 03-29 Update: Side piece includes side stopper (width 70mm).
