Wall Mounted Stack-able Filament Spool Holder

I got tired of storing my filament on the ground but also get tired of the hassle of always going through the process of swapping filament rolls as well so i came up with this idea. These are stack-able so as many as you can print is how many spools you can mount to the wall. Will work both vertically and horizontally. Fits most common filament spool sizes.

This has been designed to use a wooden closet rod through the hole in the middle. 1.375" diameter or less. Use one slider to keep the rod in place vertically and then allow for changing the rolls or print two and put one at both ends to use them horizontally. Only downfall is that it takes a while to print each bracket.

Mock up pictures do not have the closet rod in place yet ( need to buy it and cut to length after i have made all the brackets) but look at the renders for an example.
