Low Profile Undershelf Spool Storage Mount (Customizable)

I wanted a shelf mount for my unused spools. At first I was thinking about arms where I could mount the spools in print orientation and even print of shelf. Well, this would only work properly when the spool is close and above the printer.

Also when not used those arms would be dangerous for heads, eyes and other body parts. At least they would be broken off and need replaced now and then. In the end when empty, they just eat space.

That is why I created this low profile storage solution. Since I already used 10mm "screws" as spool axle, the main idea was to simply add a nut below the shelf and screw the unused spool in. When empty there is just a small bump at the bottom of the shelf that eats next to no space and is harmless for human health.

WARNING: This is not a regular spool holder. The result would be catastrophic. Do not use as a spool holder for printing. Doing so will create a 1kg time bomb waiting to fall onto your printer hitting even with more than 1kg.
