Wallmounted spoolholder

The pipe I used in the s-hook is just some leftover "pipe" with the diameter of 25.40 mm with a wall thickness of 0,85 mm.
The rod I used across is some old speaker stands that I was able to screw together to make a long rod. This has a diameter of 19,30 mm. You could probably use several types of rods, as long as it has a diameter less than 20 mm for the top rod and less than 25 mm for the s-hooks.

Instead of threading all spools on to the rod, I hang it underneath. This way its easyer to change one spool without removing the rod across.

I added the file for the wallmount, s-hook and the end cap.
