Stackable Spool Holder

I could not find what I was looking for, so I decided to make it. This is my current version of the stackable spool holder. I think I need to make the ends of the sticks a hair thicker, but getting there. It's currently functional, but it is a hair flimsy. Like I said, it's getting there. I'm currently using PETG for the print (trying to learn how it works printing wise), but I'll try PLA soon. I also need to design a spindle for this, so it can be printed from top to bottom.

Before printing, make sure to rotate it so the bottom is flat. I will fix that in later versions.

Including the .f3d files

Picture includes earlier versions (on the left). The bottom right (with the blue TPU) is the latest iteration, supporting a semi failed print that I sort of made work over it. Since the (sort of) failed prints mess up towards the end, the bases still work as stack testing.
