The App Store usually would not provide older versions of a utility such as DiskMaker X.
However there may be other reasons why v 3.0.4 'older version' for Mavericks, Mt Lion,
and Lion, did not correctly load. Other than the suggested smallest size of a Flash drive
or other partition (after partitioning, the total available for the boot disk) should be larger.
And I'd suggest -- & have read other users said -- to get a 16GB USB flash drive for this.
The formatting is essential; better if you do not need to partition a flash dedicated to this.
And while the prices of quality USB Flash drives have come down in the passing of time
the larger capacities sometimes aren't as available compared to the smaller ones.
Other ideas from the pondini.org site (from main menu) are fairly good and still apply.

Too bad DiskX' maker was unable to reply - or perhaps has a preference to support those
who have donated toward the project - I'm not sure and won't speculate further on that.
You could install to an external HDD directly if the computer has or can get the correct
OS X version from its Recovery setup or from Internet Recovery; this can make duplicate
version. To download the installer is one thing, it still would go to the Internet to get the
whole file, at least in one instance of actually installing the complete OS X. This is where
a full system clone for offline restoring of the computer's entire hard drive content, is good.
Sorry to not have any new ideas.
Here's wishing you better 'good luck' in this endeavor. 😐
