This is a starlight headliner tool that I created to make it easier for poking holes into a headliner. As anyone knows, this is a long drawn out process. Having the tools necessary to get the project done a bit neater is essential. 

The collet and chuck was created by LoboCNC, but scaled down just slightly to fit the pen and uploaded as a remix. 

You can find the model here.
 

Get the needle that you will be using for the project then once you have all parts printed, insert the needle into the collet and screw on the chuck. It holds very nicely.
