Phase 10 (Simple) - Rugged Box Lid
I appreciate the model originally created by Doohickey for Phase 10, but the added elements around the logo that make it look nice were tricky for me to print, so I tweaked it to make it a little simpler, and easier to print.
This can be printed like others - align both models in your slicer, then delete one (and slice), then undo, and delete the other (then slice again) to print in two colors - for those of us not (yet) on the MMU train.
