Gridfinity spool + holder

Spool and gridfinity bins (1x1 and 1x2) for them.Holes in the spool are 2,5mmThese spools are intended for things like fishing wire, elastics, and other small things.I didn't try it with wires, soldering wires or "harder strings" Assembly:The two halves can be held together by preassure, but I recommend gluing them together
