Custom model for the replacement of the inner barrel on the Pentel GraphGear 1000 mechanical pencil.

Initial threading is a bit tight, it is advised to pre-thread the body and tip as seen in picture three before assembling the whole pencil. This will make it easier to fit together and ensure everything seats properly. Shaft extension may seem a little tight or scratchy at first but this clears up after a bit of use, gives you an excuse the play with the click.

Model was made in Tinkercad based off the provided CAD document from reddit user https://www.reddit.com/user/muddyalchemy/.
