About this 3D model

Designed this for a friend as a gift, thought other people might like it. Change filament after 4mm (at the beginning of layer at 4.2mm for 0.2mm layer height). The signature can be made another color if you have a multi-material system. If you don't you can try removing it, which will embed the text (I haven't tested this), or you can just leave it the same color.
