Suction Cup Dildo Installation Advice or DIY Options

Been trying to find a dildo stand lately so that I don’t have to use a flat pillow and a flat plate, and I want a slightly different angle, like doggy style. However, I’m having a hard time finding one. I saw the Tom V2 and was going to buy it, but I noticed that the weight attachment isn’t even available anymore. I don’t want to have to constantly have to keep this stand in place. Does anyone know how to make a makeshift weighted bottom? If not, can you suggest something that would work as a substitute so I can DIY it? Can I use any IKEA, everyday item, or hardware item to replace it? I only have simple tools like screwdrivers, drill/drill bits, etc. So I can’t get too complicated… Thanks to everyone who offered ideas!
