Print in Place Hard Shell Magnetic Glasses Case

This is a print in place hinged glasses case. I recently bought a nice pair of glasses that only came with a soft case and I decided making my own hard case would be a great way to practice print in place hinges.

This model uses four (4) 10x5x2 rectangular neodymium magnets which can be found at the following link.

I am going for an unsupported PETG print but am struggling to make the overhangs on the case halves a decent quality while still keeping the bridges inside the hinges from fusing solid. The attached G-code file prints fine with PETG but the interior top and bottom faces of the case are a little lacking.
