This model is an easy long print, although be aware of warping! A default 0.2mm will do fine with a 0.4mm Nozzle and Perimeters set to 3. Recommend PETG, not PLA.
Used filament in the picture; Extrudr PETG color “Dessert Storm”
At first, it will close very difficult, but after 10x times it will become a bit looser and for normal use. Opening and closing this box like shown on the photo. Break it open at arrows as like there is like a hinge on the other side.
The stl files is without my callsign, you want to add your own callsign, I used Bold Verdana 7mm with 0,4mm thick.
