Filament Holder

thingiverse

I made a simple filament holder for my Ender 3 with an adjustable spacing feature that's still a work in progress as I iron out the kinks in my design. You can find the hardware I used at Menards. To make this holder, you'll need four sliding door rollers and some mounting hardware. I personally used 1/4-20 by 1-inch machine screws for the job. Edit: On March 16th, I uploaded a revised file that addresses an issue with the ends interfering with the rollers in the original design. If you don't plan on using the outer holes, this new version should work just fine for you. The second file also includes additional support for the sides and eliminates the end pieces altogether.
