Tinkercad 3D Design & Print - Pencil Extender

A pencil extension gives life to ... ... pencils. Pencils that are too short to be practically held. 

One way is to buy a pencil extender, but, it is way more cool to design and print one yourself. And that's what I did.

However, that being said, one can always improvise and use any available material(s) such as rolled paper at the end of a short pencil and some tape. But if you have access to a 3D printer and a free platform like Tinkercad, that'll make it look much cleaner and more product-'designerly'.

Below you'll see the 3D model of the pencil extender and the actual product in use. The extender has slotted 'windows' on both sides so users can 1) see where the end of the pencil is, and 2) use the slot to 'dig' an ultra short pencil out if the entire pencil is stuck in the holder. 

A regular pencil stays nicely in the holder, however I still use tape to bind the opening of the holder to make a tighter fit, so the pencil may be more stable when it's being used.







In design, there will be iterations. No matter how well the thought or plan is. As much as I wanted the pencil to work first time it is printed, reality is far from the truth.

I eventually went with version 3 (the image below shows up to version 2) where I continually modified the hole and the side gaps of the holder, with more aesthetic refinements. 


So here you have it.  A short pencil extender. And now all pencils are loved till they are no more.
