Cessna 172M pencil holder

thingiverse

In a Cessna 172M, you can accommodate up to four smokers; however, smoking isn't allowed on board. To replace the ashtrays in the front, a straightforward design is suggested. Initially, I used to put pencils and pens into the ashtrays but they kept falling out, wasting space. I learned about 3D design from wolfboy's Palomino pencil holder design and implemented it for a solution to my problem.
