Print, place a pen inside and kling, klang, klung everything!I used this polygon generator program ( thingiverse.com/thing:9290 ) to create this object. Version 2:run in OpenScad.Also, in OpenScad the view window gives an error at the spot where the nail remover is. I don't think this problem arise when you print this object.
