I’m primarily an armor modeller which is why 1/35th is the default scale, if anyone wants me to set something else as default let me know. It might make it a little more convenient to use.
Here’s a 1/72nd version:

. . . and here’s a 1/48th version:

These are just replacement executables (13.5kb), it needs the same .dll as the original scalar to run, but if you want, you can toss the original scalar.exe and replace it with one of the ones above, or you can use them both.
