I modified it a bit to allow for the belt clip and to make it laser friendly (Most leather patterns have dotted lines for stitching, where as we laser folks want actual individual holes).
I thought the main pouch a bit small, so I made a 1 inch gusset to give it more room. I also included a version of the gusset so it can be printed and put together in case you didn’t want to use the glowforge. that’s if the whole svg gets loaded. I included pictures so you can see how I put it together. I use a thick top spiral notebook, that’s the reason for the gusset.
