About this 3D model

This electric screwdriver and mini drill is designed using some spare parts. It can be used for both forward and reverse rotation. It has power display and MicroUSB charging. It is very convenient to use in small occasions. The shaft linkage parts are printed with PETG. Those who are handy can replace it with other more stable materials. I used a small gear here, which is very durable. The outer shell is PLA+, Please ignore the welding technology. You can design and modify it according to the small parts you have. Also, please feel free to give me your suggestions. Parts List: 1. 688Z Bearing 1 piece 2. N20 Reduction Motor 1 piece 3. Limit Switch 1 piece 4.
