Khe gió tản nhiệt cho Arrows Viper

I designed this simple cooling vent to be used on my Arrows Viper and without being scientific it does help keep the battery much cooler.  Along with the vent I made a template to allow for a perfect fit.   Simply hold the template where you want the vent to be, trace around it with a pencil and cut it out with an Xacto knife.  Once done add a few drops of Foam-Tac or whatever glue you use and you're all set.  I have one mounted on each side of my model.

I have uploaded the files as a set and individually in case someone wants to resize the print to suit other models.
