This is a re-work of a previous design of mine that cleans up the outside and makes the weight component interchangeable. Once printed you can put any form of weight in the center of the plug, I used pennies but nickles or glass beads would also work great, and then screw it into the base. If you ever want to change the weight you can just unscrew the plug and remove some of the weights. I personally hot glue the weights into the plug so they cannot shift around on me so when I want a different weight I just print another plug piece and weight it differently. To use the stand you just stick some poster tack (https://www.amazon.com/Scotch-Mounting-Putty-Removable-860/dp/B000AN7EW4) to the top and stick your model to that.
