Dan, did you print the original case or the one with the opening?
Mine fits perfectly when using the case with the opening.
If it still doesn't work, don's email me! I'm just the guy who saw a need and opened it up to the community!
@weird_w I'm thinking there will be people who could use different cases. Heck, there are probably people who could use a full 4A case! So, if you like tinkering with stuff like this, knock yourself out!
Here's a thought, how about that gear in the printer/plotter that keeps stripping out! I know several people who'd be all over that one.
