Yet another empty spool storage bin. I designed this one to fit AMZ3D spools. Also included a a part to allow spools to sit on top of each other. Uses 1/4-20 screws (I used 1/4-20 button heads 1/2" long from both sides) or equivalent metric (which I have not tried)

The Two blue bins were printed on my MP Select Mini V2 and the two yellow ones on MY Anet A8. (originally designed to fit a 110 x 110 mm area)
