Chair Headrest

I have an office chair (brand unknown as it is a hand-me-down) that has three screws on the back for mounting a headrest. This is an attempt at making the headrest. I have not printed it out yet, as some of the parts are too big for my printer, so I will have to wait until my work printer is available.

You will need to print two of the thumbscrews (these are for optional height adjustment).

The parts all slide together with the exception of two parts - the long holes will line up and are meant to house a metal rod in each one. I am hoping that this will increase the strength of the parts when resting my head on the headrest.
