Simple Eye Glasses Case.
Use 8mm magnets.
Hing works well using the solid core copper electrical cable with the insulation removed. Also had some luck with Sate sticks, but these will expand when wet and crack the hing.
Update: The Inner pad is printed from TPU and sliced without the top and bottom layers which exposes the infill. The extrusion thickness for the infill may need to be tweaked to make it more giving/flexible and the infill % may need to be lowered.
