Dog bags holder with a bags retracting feature

OK, I know that there are quite a few dog bags holders on Printables. But I missed one important feature among them - when you pull bags out usually it is not very convenient to roll them back into the container.

Here is a holder with a lid which allows to rotate it together with a bag roll (no theread). I designed it for my Purlov rolls with a hole diameter = 7,9 mm (to fit tightly). 

Additionaly I have also designed a button (print in place) which allows to hold a roll from outside and to be able to retract bags in case if a bags roll is not tight enough on a spinle. If you need a different spindle diameter, write please down in a comment - I can add it (I use only one kind of bags and do not now how about others). If a hole in your roll is bigger - just use an embedded button and it should work, too.

I like to hang it on my neck so it is designed for that purpose (to mount on a paracord).

MATERIAL: I used PLA and it looks fine.
