I am also after are 4X4 wildfire unit being made into a key ring also, but can not get it to work through Makerlab key ring designer, frustrated

Hi Community, can anyone help me out. I have been trying to make some simple key chain items based on the fire appliances we have in service and failing. Can anyone help guide me better or even make the file, as the service has a open day soon and would like to give away or sell for the charity.
