About this 3D model

I rebuilt the model from scratch but the idea came from fafabienman. I added a pocket on the left side to put the BT-168 battery tester. Having the tester in the upright position also increased the storage capacity considerably. The bottom slope has also been reduced because it saves a lot of useful space. Otherwise this tester is very useful and can be purchased cheaply on popular online marketplaces. I also really like the original design and appreciate that such simple things can be popular. I used PETG for the durable part.
