Elegoo Mars Prints

Have gotten back to using my 3D printer an Elegoo Mars.  Months ago gave Tinkercad a try and came up with a simple coin design.  This is what I printed.  Well seven of them.  Once I the model how it need to be on the build plate it cloned it over six more times.  When I design it use the dimensions of a toonie.  Thinking it would keep the same size.  However after the print stop seen that they were much smaller.  So going to give it another try and up the size scale a bit.
