This model is a 2-part container that screws together to display flat discs called POGs which were popular in the 90's.  You can print your own POGs here:

There is a text file attached which lists POGs in the 7 sets.  POGs were designed to be printed with an MMU.  

When the container is printed in black, it reminds me of a car tire.  So I also created 5 wheel cover designs.  With these, the visualizer looks like a rotating car wheel.  These DO NOT need an MMU to print.

I use a 5 mm brim to print the container bottom for more stability while printing.  The top has a small indentation for an 8x3 mm magnet that may need support when printing.  It's not very deep so it's easily removed.  Both top and bottom are printed with the threads up.  A 0.2 mm first layer height and 0.1 mm thereafter made for the best threads that worked every time for PLA and PETG.  I also used an infill of 15%.

There are 5 wheel designs included here.  Like the POG's they are also printed with 0.2 mm first layer and 0.1 mm in all other layers.
