I wanted to store my filament boxes laying horizontally but everytime I need a box in the bottom, I have to take them all out to be able to reach for the bottom box and then put them all again in their place. So, I decided to design a rack system so I can store them all laying horizontally without that issue.

My first objective was to make it not require TONS of filament and I think I was successful with that. Each “rack structure” uses around 95g of filament, and the “top part” (which you only need for the top-most part of each column) uses around 45g of filament.

I also added the option to snap each column to each other. For that, you need to print the plate with the small pins!

     How to build your filament rack:

1. Print two or more “rack structure”
2. Make sure to align the pins on top of the “rack structure” with the holes in the bottom of the other “rack structure”
3. Repeat untill you are satisfied with the height of the column of your rack
4. Print the “top part” and attach it to the top of your column by aligning the pins with the holes
5. If you want to snap a column to a new one, print the plate with the small pins!
6. Place the pins in the holes located on the side of each “rack structure”
7. Align the pins with the holes of the “rack structure” of the new column
8. Enjoy!

There's also some optional “feet” for the bottom "rack structure" but they're optional, I only made them in case someone prefers to have them in the bottom of the rack.

The inside measurements are: 22.5x23x9cm

In case you need a slightly taller version, there's also a print profile with: 22.5x23x10cm

I think that's all. I hope I didn't forget anything. I hope you enjoy it! :)
