This is a mashup of multiple thingiverse parts. Mainly props to InnovationByLayer's Doctor Who Dalek thingiverse.com/thing:1600. I've added a Coin-op Bottle opener modeled after Hoeken's variation thingiverse.com/thing:1813 . Finally, I've tacked on the thin profile whistle from TeamTeamUSA thingiverse.com/thing:5416 (Take that Makerblock! makerblock.com/2011/01/your-argument-is-invalid/ )

Something for college football fans. I drew up this block O buckeye logo to stick on a keychain. I haven't tried it on a keychain yet so I hope the hole is large enough. If not, it can be scaled accordingly. The part is only about 1 3/8 in. tall (drawn in inches).
