folding pen holder

I have designed a versatile storage tool. When you bring this pencil case to the workplace, you can neatly arrange various pens for easy access during work. When the work is completed, you can take the pens out and assemble them into a pencil box mode, placing it in the backpack to prevent them from being crushed.-------------我設計了一款能夠兩用的收納工具,當你帶著這個筆筒到了工作場合,就可以將各種筆放置好方便在工作時取用,工作完成時就可以將筆拿出組合成鉛筆盒模式放入背包中,避免壓壞 Originally, I wanted to design it to accommodate watercolor brushes as well, but since I only had the A1 MINI for verification, I used the A1 MINI's maximum dimensions as the size for this project.-------------原本有想要設計成能夠放入水彩繪圖筆也沒問題的尺寸,但因為我手上只有A1 MINI 能驗證,所以就先以A1 MINI 極限尺寸作為此作品的大小
