Edit: This thing has been driving a 50 sheet punch for thousands of students for over a year now! I honestly cannot believe how well this held up. I'm wondering why the original one broke.....
Our Swingline 350 MD main drive gear had a few teeth sheared off (see pictures) and the parts are now out of production. 3D printing to the rescue! To my amazement, this 100% infill PLA printed gear has now been in service for close to 6 months being used by hundreds of university students to punch
