I am a teacher and I got tired of replacing these $90 pencil sharpeners every single year because this gear wears out, so I designed one and ordered it. Worked like a charm and much higher quality than the original gear, which is a flimsy piece of junk, notorious for wearing out and leaving you tossing your whole sharpener. Changes out in about 10 minutes and you [should] never have to throw this thing away on account of this one little part. The one pictured was the "Beta" version. All I did was add holes to this release so it would be cheaper and a tad more flexible to install. It still has the same strong teeth as the original. A 79 tooth gear with a pitch radius of 29.5 mm and thickness of 5mm, a 12mm diameter hole with a 2mm wide offset bridge.
