Voopoo Argus A Vape mod case

Someone needed a case for their Voopoo Argus A vape and wasn't able to find anything online. I'm still new to creating stuff in CAD and used Fusion 360 to make the versions in the files. The V1 file is just the plain case with no holes for buttons or chargers. The V2 file has a hole for the top button on the side. File V3 has slots for the charger, button, and air intake on the sides. I have test fit this printing in PLA and it fits snug, but not overly tight. I plan to print these in PETG for better durability. Please boost if you like this. Also let me know of areas where I could improve on the design.
