Puzzle One

After doing several other puzzles on here I decided to make my own. Some credit for inspiration and methodologies to Stewart Coffin. This is an original puzzle and the first one that I have created so it is titled Puzzle One, exceptional creativity I know :)
Tolerances are baked in, printing at .2mm resolution is fine. If the piece fits in the frame you shouldn't have any issues fitting the solution in(that spot has tighter tolerances than the solution).
I'm not sure it's all that difficult, but I did make the thing and since I only see the solution I'm not sure if I'm qualified to make that assessment. Please post feedback, positive or negative, with your make or PM me if you have issues.
