My googling skills seem to be failing me, so I'm turning to you to ask if anyone can kindly help

I'm looking for PCB foam for my 2u left shift 60% build on a XD60/64 PCB, specifically the layout attached.
I've checked KBDFans, KPRepublic, AliExpress, and StupidFish, but none of them seem to do this layout.
I tried cutting my own with a cutter, but because I'm using MillMax sockets, even small imperfections result in the switches not being seated correctly and popping out (and my imperfections were more than small), so it hasn't been a great success.
Does anyone have any leads? I'm in Europe, so I would need it to ship here for non-extortionate shipping costs
