Weighted Engineer's Pen Cup
Description
My Father Asked If I Could Make A Cup To Hold A Single Pen Or 2. He Wanted It Weighted And Conical. When I Whipped This Up For Him, He Said "That'S Just Like The One I Had On My Drafting Table In The 70'S!". Bottom Of Cup Is Open To Take A 51Mm Od, 21Mm Id, 3Mm Thick Washer. It'S Probably Imperial Sized, But I Didn'T Bother Measuring.
