Connecting Rod Bottle opener split pattern for sand casting
Description
I Made This Sand Cast Connecting Rod Bottle Opener. This Part Is A Split Pattern For Sand Casting, It Has A Minimum Of 5 Degrees Of Draft On All Surfaces To Aid Removal From Sand Molds. It Should Be Printed In Duplicate, And Assembled With 2.5X6Mm Pins In The Far Holes. I Have Reduced The Gap Between The Opening Blades To 15Mm To Improve Function. The Pictured Pattern And Castings Have A 20Mm Gap, Which Is Too Wide And Can Grip The Glass Lip Of The Bottle.
