This collection of filament spool holders is designed for cabinets, drawers and shelves and comes in a range of sizes, allowing you to optimize your storage space efficiently. Each part has been meticulously tailored and reconstructed, rather than merely scaled down, ensuring that the desired width is achieved without compromising the holder's stability or aesthetic appeal.

In order to prevent the spools from toppling over while using this holder on a pull-out shelf, I have introduced versions featuring a small wall on one side.

Compatibility

This holder is designed for spools with a diameter of 195mm or larger. While it is possible to store smaller spools, they may not align as tidily.

Printing instructions

Please note that this model type is prone to warping. To minimize this issue, it's crucial to use an optimal sheet surface suitable for your printing material. I recommend using a spray adhesive to enhance adhesion. Also, be vigilant in maintaining a consistent temperature during printing to prevent warping. For PLA I recommend using a smooth PEI plate (not the default textured plate). For best results and troubleshooting tips, I suggest conducting a basic online search on 3D printing warping before attributing any issues to the print profile.

Installation IKEA Pax

The featured image displays my recently completed IKEA Pax Filament Cabinet. It is equipped with four pull-out shelves, each measuring 90x57cm, utilizing full extension slides. Each shelf accommodates three rows of spool holders, with each row capable of holding twelve 1kg spools, summing up to 36 spools per shelf. The rows are uniformly spaced across the shelf's depth, maintaining a 2cm gap between rows and a 2cm space at the front and back. This layout enables a slightly overlapping arrangement of spools across rows, facilitating an extremely dense storage solution. To prevent the slides from interfering with the cabinet doors, I tapered the cabinet's sides. The materials were selected for cost-effectiveness, using the most affordable lumber available at my local hardware store, measuring 6x1.8cm and 2.5m in length.

The Bill of Materials (BOM) for each shelf board is as follows:

• IKEA Shelve Board: 10€
• Full Extension Slides: 20€
• Lumber: 2.50€
• Three Rows of Spool Holder (1.2kg of filament - Jayo PLA Meta White): 10-12€
• 3M Double-Sided Tapee (19mm width): 1€
• Screws: <1€
• Total Cost: ~45€

Time Investment per Shelf Board (excluding material procurement and printing):

• Measuring and Wood Cutting: 30 minutes
• Shelf Board Installation: 60 minutes
• Spool Holder Installation: 25 minutes
• Total Time: ~120 minutes

And to address the inevitable question about the abundance of filament – yes, it's a bit of an obsession.
