Another spoolholder

I wanted an enclosed spool holder that didn't cost an absurd, kept the holder stable, and could hold all spool sizes I use.
Maybe over engineered, but I like it.
The best part of it really is the cake container. Bought it in a garage sale for $1.
I am placing a PTFE tube to the printer enclosure to keep it neat.
Someone suggested venting air from the printer enclosure into the spool holder enclosure.
Assembly is very simple, as the carriage is kept in place by the screws attaching the gadget body to the container base.
I will love to hear comments and suggestions to make this design better.
