Hello everyone, I'm here again. I 've been sorting out the hard disk recently and found many works interesting when I was young, so I sent them out to share them. This is a work of June 2018. The performance technique is not enough. I'm sorry. The design prospect of this work is to find a phenomenon: it is difficult to take out the eraser or staples in the pen container, so we designed such an "open belly" pen container. Until now, there seems to be no similar products on the market. I don't know if any boss is interested.

Very convenient, very good
This is very useful, but the actual experience is still not ideal. I printed one in 3d and found that the pen is not as clever as I imagined.
If you design it yourself, do you have to apply for a patent in advance?
This is really super convenient
I like this!!!! It's super annoying to find erasers every time.
