Gear for a toothed transmission.

Made to replace the gear in the 3D scanner project on the Creality Print website https://www.crealitycloud.com/model-detail/63219dea0a1d6ba10fefc4f1?source=26

Taking this opportunity, I would like to once again thank Vik3D for the 3D scanner model files.

Reasons for modeling a new gear:

1. The gear model attached by the author is not suitable for printing and use: the inserts with square holes in the center of the gear on the model are not connected to the gear body.

It is impossible to install the original gear without gluing the insert into the center of the gear.

2. The insert with a square hole is too narrow in width, as a result it moves along the tetrahedral shaft of the manual drive, the gear disengages.

3. The gear model attached by the author is too narrow. In combination with the small width of the teeth on the bottom of the table, it easily disengages and slips.

I made the new gear wider and more solid. With such a gear, the 3D scanner table rotates normally. For comparison, attached is a photo of the new gear made of green PETG and the gear model I printed from the author's model (gray PETG), as well as photos of the location where the gear is installed.

Printing with a 0.4 mm nozzle, 0.2 mm layer (0.2 profile in the Creativity Print 5.1 slicer), 2 walls. Infill can be set to 15% -25%.

Printing is horizontal, with the side plane on the printing table.

No supports or skirts are needed.
