Ecoflow alternator key holder

Needed a way to hold the key for the Ecoflow alternator charger, because it is easily lost.The fit is quite tight and I did have to sandpaper both the bottom and the sides so it slides back and forth easier.The model has a notch on each side where you put the key in, to hold the key in place so it don't fall out. I put double sided adhesive on the back to attach it to the alternator charger. As most of my designs it is designed in tinkercad because it is the easiest cad software to use for my needs.It is printed in generic pla, you may use petg or other filaments if you want to.
