Here are two versions of an inner scalloped frame by request. These files could be used as frames, or welded to an aperture card for a scalloped aperture. 🙂
The download is a zipped folder with svg files for use in either version of SCAL. These files are for personal use only. Feel free to link to this post, but the files are not to be shared or distributed in any way.
Download the files from here.
