120 Takeup Spool for 35mm Film: Remix without supports

The original design (http://www.thingiverse.com/thing:522005) cannot be printed without supports and i don't like supports. A friend of mine needed this thing (I am not a camera expert) so i splitted in 2 parts in order to print top and bottom separately.

The tenons are actually a bit smal but it should be ok as constraints are in compression.

I used blender to design the joint.
