With my Printrbot up and working, I am trying to find interesting uses for it. I recently had the idea of creating a small charm (elephant/heart shape) for a necklace. The only issue with a small piece like this is the need for a smooth finish. After some looking around, I think I plan to go with an acetone brush-on solution. I am planning on sealing off the charm and getting rid of excess filament with an acetone-based nail polish remover. I will report back on the success of the process after I finish. YAY!
