Reel Winder with Airsoft Pellet Bearing

I got the idea from https://www.thingiverse.com/thing:2545697 , but this was to big for my printer.
So I made my own smaller size that is only 14cm wide and fit a 50m nylonline/rope.
I mad this to have with me if I crash my drone in a tree.
You need:
5 pcs of 3mm bolt with a length of 10mm
5 pcs of 3mm nut
5 pcs of 3mm lock washer
42 pcs of 6mm airsoft pellets
