Print in TPU. Low infil will keep the bottom squishy, 20% or so.
These were designed for 2 inch HPA paintball tanks as a grippy protective cover. I have a 15/4500 FirstStrike tank that I have modeled the 15_4500 STL files off from, but I do not have a 13/3000 to test the other file. It should work as it has a more squared off bottom than the carbon fiber tanks. Please, if you print the 13/3k and there issues, let me know so I can fix it.
Files:
13_3000 short is for aluminum 13/3k tanks
15_4500 short will work on any FirstStrike carbon fiber 2 inch tank as a tank butt grip
15_4500 tall has a large window to see all of the tank hydro info
15_4500 tall small window has a smaller oval window to just view the hydro date
15_4500 tall no window doesn't have a hole to line up with your hydro info. That information isnt important anyway.
