Intro: Triangle Pencil Cap
Triangle Pencil is a good instrument for writing.
However, sharp pencil is a potential danger for the young, especially several sharp pencils are placing in small pencil box.
I need a pencil cap but I can't find it in local store, so, I made it.
Materials and tools :
2. a sheet of Memo
3. Some sellotape
4. Some Blu-tack
Step 1: Improvement
Pencil cap made of paper can not last for 1 week...
So, finally I made this plastic cap insert in hot shrink tube, it is a bit difficult, but I share here as references.
