I added a third channel for an extra hair tie to keep cards from coming out of the wrong side on accident. One note about this…there are two versions. One version if you want to pull cards out using the cutout, and another version if you want to push the cards out using the cutout. I also added a small chamfer to the inside to make inserting cards a little easier.
Update: I added a money clip version and a money strap version, in both left and right handed versions.
Update: I added left and right handed versions which accommodate an AirTag ("push" versions only). The AirTag just snaps in from the inside of the wallet. Since the AirTag part had to be thick enough to accommodate the AirTag, I also added a hidden compartment in there where you can keep a couple ibuprofen or some allergy pills or something.
The author remixed this model.
