Classic Cassette Model for 3D Print 3D print model

This is an accurate classic cassette model for 3D printing. It measures 100mm long, 6.4mm tall and 12.5mm wide.I made 3 versions to ease 3D printing process.First version (cassette.stl) it's the easey 3D printing model, it has holes filled in order to ease 3D printing process.Second version (cassette_hollow.stl) it's a physically accurate cassette model, for expert 3D printers that can use their own software supports.Third version (cassette_hollow_with supports.stl) it's also a physically accurate cassette model, but include pre-modeled suports in the tricky holow parts of the model.
