Mechanical Power - Hand Crank & Large Gear (Installable on Jiuhu model)

Mechanical dynamic style hand crank and large gear for @十七酱's Diligent Wine Fox model
(This is how it should look (crossed out))

I helped a friend print this Wine Fox model, but felt the original gear was too large, so I modeled a mechanical dynamic style gear and crank using CAD. The ratio is consistent with the gears and crank in the Wine Fox model (2.6mm per pixel), allowing for a perfect replacement. However, they cannot be used for transmission, as you can't clip through models in Earth Online (

It is recommended to print shaft parts using PETG for better toughness and wear resistance. Other parts should be printed with PLA for a better texture
 

Note:

The round shafts are all chamfered for easier installation, but the assembly tolerance is very small. If the material shrinks too much, it won't fit. In this case, you can enlarge the hole by friction with an electric drill or adjust the model's scale

The decorative parts are very tight. I tapped them in directly with a nylon hammer. If you find that excessive shrinkage prevents installation, you can try gently heating them with a lighter. After softening, gently stretch them, and they should fit
Since the shaft is long, do not force installation to prevent breakage. It is recommended to use a C-clamp to press them in vertically
Remember to lubricate the shaft parts!
