This is a holder that digs into the ends of a corn on the cob, in order to hold it while eating. You need to print two off, one for each end. I printed it in nylon, but other materials will be okay, I just haven't printed it in any other material. It should be printed standing up on the print base. It may need a brim to keep it secure while printing but it doesn't need any support. UPDATE+++++ I have upgraded the design to have a spiral on the tapered part, so that it screws into the ends of the corn cob. I have replaced all the files with new ones.
