3D model description

I have uploaded them two days ago. But they are not shown on my design page. I think they can be seen anyway. But it seems not correct. Now I upload them again.

Summary
I have designed the first straight one-way manual hand drill in the world several days ago. It is powerful and handy. After I have used it especially from the fan’s comments, I realized that I can upgrade it a little for better usage.
No. 1 Handle part
I change the handle part to a screw fixed part. It is easier and convenient to use
No. 2 Add different drill size option
I add the different size of drill which covered the 0.8 to 4.0 mm.
No. 3 Modified a little at the stall coupling part
Enlarge the space between the small cylinder space. Now it is easier to couple them together between the cage and nuts.
