3D model description

Check the dimensions of your phone against the slot dimensions pictured - I designed this for smaller phones like my old Samsung Galaxy S2, so you may want to scale up the design prior to printing if you're using a giant phone.

Read more about the design of this product on my blog, including the multi-coloured effect created by swapping filament colours during printing.
