Parameterized Stackable Chip Rack

3D printing files for a fully customizable, stackable rack for poker chips and coins.
Printable without supports on printers that can do 45 degree overhangs and a few cm (depending on chip size) of bridges.

This rack was inspired by the the effort of Rubén Torres on BGG to bring Ceramic Mini Chips to the masses.
I created this model while waiting for my shipment.

The rack can be configure to have any number of rows of chips and any number of chips per row.

The rows can be configured to have any depth up to 50% of the chip diameter (any more and the row would get narrower at the top and the chips wouldn't fit in.)

You can also have "bottom rows" on the underside of the rack, so the racks can stack.
The bottom rows aren't rounded but have 45 degree walls (and bridges at the top) for easier printing on most 3D printers.
If you don't want stacking, you can configure the bottom_row_depth to be 0%.

You can configure the "top rows" can be configured to 0% depth to create a
