Mini filament spool

This model is based on Johannesbehr mini spool http://www.thingiverse.com/thing:129173 and esun spool combine what I like about each and voila get the spool the way I like to use with my loose filament. From Johannesbehr design I use the dimension and the guard idea from esun spool I use the screw to attach it together that way avoid me designing two different parts and also to glue it. The spool hub is 32mm which fit nice in my printer. If you print it keep in mind that this is a small spool that only hold a max of 50g of filament.
UPDATE files have 1mm thickness in the walls
