Retractable Rosin Case

This is a rosin case that extends and retracts the rosin using a screw. It is suitable for Hill rosin that comes attached to a piece of fabric with an elastic band. I would often drop my rosin or knock it off the table, invariably damaging the rosin - until I made this case,

You will need:

* A machine screw, #8x24 or #8x32, 1 1/2" long;
* Two #8 nuts;
* A #8 brass insert matching the thread count for the screw you're using (I used **[these](https://www.amazon.com/initeq-Threaded-Plastics-Assortment-Printing/dp/B0771W9M6R)**);
* A reamer;
* Some Loctite Threadlocker or JB-Weld;
* Some adhesive for plastic (I used SciGrip #16);
* A hot glue gun.

After printing the parts, assemble everything using these steps:

* Insert one #8 nut into the hex-shaped recess in the 3D printed plastic nut.
* Insert the screw into the plastic nut from the other side, and screw in all the way until it's tight. If you want you can apply Loctite to the #8 nut, but it's probably not necessary.
