Have you ever received SLA, PLA, or ABS 3D-printed parts that cracked or broke during shipment? If you’re considering these materials for mechanical engines, Think different. A gear needs to be engineered to withstand harsh conditions and resist breakage under heavy strain. That’s exactly what I’m offering.
6x GEARS for 800K or 2MB SONY FLOPPY DRIVE MP-F51W, MFD-51W & MP-F75W
Made in Italy Gear to repair a non-ejiectiong Macintosh floppy drive
This little gear is the perfect spare better then the original, it's been produced by injiection molding as the original is been done and not with any 3D printer repro. The OMRON eject mechanism is present in both of the 2M and 800K Macintosh floppy Drive ( SONY MP-F75W, MP-F51W or MFD-51W). I repaired dozens of these drive in the last years testing the quality and durability of my solution, i started this gear project in the beginning of 2015 publishing some references into Macforum.com by December of the same year.
Gears updated today in May 2024 are improved by an updated steel mold for the material used with the injection molding; i use the POM (polyoximethylene) that is one of the best thermoplastic for gears, it gives to the gear a self-lubricating, durable, rigid appearance with reduced friction that improve the overall life of the OMRON ejector mechanism. There was nothing wrong with the previous gears, but I decided to improve them after more than 10 years with the aim of reducing costs in favor of the trust I continue to have from all classic Macintosh computer enthusiasts all over the world.
Through the injection molding process, it is possible to create gears that can just perfomr better any 3D printer, guaranteeing unparalleled performance and durability. While polyamides have been the go-to material for gears over the past decades, the today evidence suggests their degradation after their aging of 20-30 years.
The Macintosh will remain operational and fully functional with its floppies for many years to come; it is a true piece of history to be preserved. ^_^

To easily repair and replace the gear, only two screws (+) and a plug need to be disassembled from the drive
The following pictures serve as examples illustrating instances where the gear needs to be replaced. Take note of the dark-orange color of the last gear, which is completely destroyed, indicating its advanced stage of oxidation:
Below are images depicting the before-and-after scenarios with the new gear. Exercise caution when unplugging the metal plate by using a small flat screwdriver to gently maneuver the rigid black-plastic hook:
