I made this Stylophone case and thought I would share it here. It has both print in place hinges and a latch to keep it closed (which could be improved but works enough for me)
I printed it in PLA 15% rectilinear infill, 2 perimeters and organic supports. I placed it with the top with the text flat on the bed and supported a couple of lines of the bottom part to use less material.
The author marked this model as their own original creation.
