ngl i just approached a bunch of random cn manufacturers and asked if they do thicker acrylics stands (;;w;;) which isn't too hard (it's all about the diligence), I personally think the hard part is finding one that has a low MOQ for your budget (minimum I can find personally is 50 pieces) (I don't mind ordering a ton of anzus because I can give them away or sell them if I'm desperate to get rid of stock since there's interest for anzu goods)
