Added a "Base_mid.stl" for those of you who wants more than 4 rolls. This part makes it possible to enlargen your stand by placing this part in the middle and then using rods that are 200mm long instead.
This idea came up when I ordered a set of four color 26AWG wires, 10 meters each, from a Chinese Ebay seller. I received the wires just as is without any spool or something to keep it nice and tidy (figures), so I went full on and designed a nice stand for it.
I made it capable of holding four spools of 26AWG wires, but hit me up on the comments and I'll make it compatible for other specs too.
The only hardware you need is three 5x100mm steel rods (just Ebay it for a small sum).
As it might be a bit of a hassle to manually tread all the wires onto these spools, I made a tiny pin that you can hook up to a drill or a screwdriver (check the pictures) and simply let it spin while threading the wire. Just print the Threading_bit.stl and Threading_pin.stl and use a M3x16-20 to attach it to one of the spools.
