Swingline Electric Stapler Gear Key

thingiverse

My office at work has an electric stapler that periodically jams like any stapler does. To clear it, a clockwork key is used to manually advance the mechanism that's included with the stapler. However, the key went missing and Swingline, the manufacturer, doesn't offer replacement parts. A new stapler would cost around $200. I reverse-engineered a different key for the same model to create a replacement. This was done for the 520e stapler model but should also work in its replacements, the 50201 and 50204. As this is an entirely functional part, it's not patentable and hereby released into the public domain. Print Settings Printer Brand: CEL Printer: Robox Rafts: Doesn't Matter Supports: No Resolution: 100 microns Infill: 50% to 100% Notes: ABS filament. The model is optimized for shrinkage and tested. I would recommend against PLA due to its brittle nature. Print with the flat side of the key on your print bed. Given the small size, high infill is recommended. Post-Printing The printed key next to an original cast in mild steel shows that the key that went missing was cast in bronze.
