This is a bracket kit for making a fun and colorful filament rack! It includes 8 brackets (4 upper corner and 4 lower corner) and 4 feet. It utilizes 2020 aluminum extrusion that can be purchased on eBay, Amazon, etc., and it is quite inexpensive. The size is fully customizable, but I will provide the sizes and parts that I used, as a reference. Yes, you can also just buy the plain 2020 brackets to make this filament rack. I designed these brackets and feet as a fun way to use my 3D printer and add some color to the rack!! After all, you have the printer, might as well use it!

To make it like I have shown, you will need:

4 Upper Corner Brackets

4 Lower Corner Brackets

4 Feet

48 M5 x 8mm long screws

48 M5 T-slot nuts for 2020 extrusion

4 legs, 2020 aluminum extrusion, 12" long each

4 filament support rails, 2020 aluminum extrusion, 27" long each

4 cross braces, 2020 aluminum extrusion, 5.5" each

I won't go super detailed into the assembly. You can see how it's made from the pictures fairly well. I have also included detail shots from CAD showing the corner layouts. You'll assemble the corners using the screws, and the feet need to be hammered on for a tight fit. Due to variation in tolerance of the aluminum extrusion, you may find that the feet are loose if the extrusion was made small. If that is the case you would need to slice your own files and shrink the feet by 1% or so to get the fit you need.

The distance between the upper and lower rail should be about 9" to give enough room to get the spools in and out. This design holds about 20 standard spools. Feel free to make it longer or shorter or adjust and dimensions as needed. If you make it too much longer, you'd need to add supports in the middle. It could go a bit longer, but I am not sure how much.

It will require cutting the aluminum extrusion. If you don't want to cut it, you can spend a little more and get pre-cut lengths. There are common sizes available that are close enough to my design to work properly. (150mm for the 5.5", 300mm for the 12", and 700mm for the 27". They are not exact but close enough to work, and available already cut)

Here are some examples of what to buy to make this:

This is way more hardware than you need, but an example of what to buy.

again too much extrusion, but it's cheap in bulk, and you'd probably find another use for it later!! I use it all the time for various projects.
