What to Do with Old Filament Spools

3D printing is amazing! Printing in three dimensions has opened up a world of possibilities, literally allowing us to create anything we can imagine. However, like many good things that come to us, comes with its fair share of waste. Such as empty filament spools that are not only non-biodegradable but also take up space and contribute to pollution in landfills. Fortunately, there are tons of creative ways you can repurpose old filament spools instead of throwing them away.

Here, we’ll explore some of the coolest and most innovative ways you can put these spools to use and make something useful out of something that otherwise would have been tossed.

1. Building Blocks

You can easily stack up old filament spools just like legos to create any unique building design using the circular discs on either end of the spools. You can even paint them and create sculptures, short walls, or a fancy backdrop for your next photo shoot.

2. Wall Decor

Spools can make an excellent wall hanging for organizing keys, jewelry, or mail. With a little bit of creativity and DIY, you can make a fantastic wall decor out of the filament spool instead of just hanging empty walls. For instance, by gluing some tiny clothes pegs or hooks, and a bit of paint, you have a beautiful, minimalist wall hanging.

3. Cable Organizer

Most people struggle to organize their tangled cords, power banks, earphones, etc. You can solve this problem with old filament spools! Poke a hole through the center, and then wrap the cords around the spool to keep them compact and organized. You can even label them so that you know which cord belongs to which device.

4. Desk Organizer

The filament spools can also be used to create an innovative, fun, and functional desk organizer. You can stack up the spools and glue or tie them together with a string or a ribbon to create a multi-level desk organizer that can store your pens, pencils, clips, stapler, sticky notes, and other desktop items neatly.

5. Plant Holder

If you’re into gardening and growing seeds indoors, you can use the empty filament spools as small planters. You can decorate and paint the outside of the spools and plant some plants or herbs in them. This unique planter not only looks great, but the plants will thrive in this biodegradable planter – when the plants get big, and you want to change the planter, you can compost the filament spool without harming the environment.


An empty filament spool is not a useless item to throw away – in fact, there are many wonderful ways to get creative and repurpose this plastic item in a fun and practical way. From building blocks and wall decor to cable organizers and plant holders, these are simple and stress-free solutions that you can try for yourself at home.

Let’s start with these ideas to help reduce waste and foster creativity!
