So I finally bought an Ikea Detolf display case for my MOTUC and 200X figures (!!), and am looking to replicate the Power-Con display style:

The only risers I am aware of are offered by Collecting Warehouse (this link), but these are unfortunately not within my budget.

Is anyone aware of another vendor who offers these risers or something similar, for less? Or does anyone have extras they're looking to get rid of? I need three.

Any help/advice would be much appreciated.
