chainsaw chain box

When i buy a spare chain from my still chainsaw i get the chain in a cardboard box. When i use the chain in the field i realized the need of this thing. Sure you can by originals from still but what's the fun by having a 3d printer then.

To give this box a little extra a make some kind of counting system. There are 2 dials that have a small notch in it. In the box there is a pin with a small boll. I test fit this and with normal pla on 210 °c it is string enough and gives a nice tension on t
