Sprue for 3DBenchy

This is a sprue designed for investment casting a 3Dbenchy in a 2.5 inch flask. I printed this polycast (polysmooth) and smoothed it using IPA Post-Printing Poly smooth Mine was printed in polysmooth. I put it in an inflated ziplock bag with rubbing alcohol and shook it for about 10 minutes to smooth it out. you could do the same with ABS and acetone.
