About this 3D model

This is my first coin top, the dollar rough cut. Its a simple little top that uses four $0.25USD coins (quarters) as its mass, thou some other coins may also work with a bit of scalling of the object. It is also support free, but you may need a brim if you have poor bed adhesion. Each good spin lasts about 2min. spin it on a concave mirror for best results. My print settings: using .4mm nozzel on an ultimaker2 layer height: 0.1mm, thou the finner the smoother it will be. shell thickness: 0.8mm infill: 25%
