Dremel 3D20 Idea Builder Lid Riser

Just a simple riser to allow use of larger external filament spools on the 3D20 or Flashforge Dreamer.

No, they don't stack, I would have made them stack but this is my first draft and it worked well enough. They don't have sloppy tolerances but it gets the job done.

I designed a guide to fit in the slot in the printer but it caused too much friction. The small section of plastic straw taped on with some slack is very reliable and causes very little friction.
