Metal 3D printed spare gear for the shredder.

The part was 3D printed using metal powder. The mating shaft had slots, but we couldn't measure them because the shaft was fixed and there was no access to the necessary equipment. Therefore, we decided to make an internal adapter sleeve made out of plastic for a rigid fit on the shaft. To avoid the sleeve turning in the gear, both the sleeve and the hole for it were made hexagonal. The use of metal 3D printing made it possible to produce the product in 2 days, as well as to make grooves with sharp internal corners without using special equipment. The printing time is 1.5 hours.

After the print was finished, no additional processing was applied.
