CoinTop: Dollar roughcut

myminifactory

This is my first coin top, the dollar rough cut. Its a simple little top that uses four $0.25USD coins as its mass, but other coins may also work with some scaling 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 two minutes. Spin it on a concave mirror for best results. My print settings: I used a 0.4mm nozzle on an Ultimaker2 printer. Layer height was set to 0.1mm, and the smoother it is the finer it will be. Shell thickness was 0.8mm, and infill was 25%.
